Description. parfor loopvar = initval:endval; statements; end executes a series of MATLAB ® statements for values of loopvar between initval and endval, inclusive, which specify a vector of increasing integer values.The loop runs in parallel when you have the Parallel Computing Toolbox™ or when you create a MEX function or standalone code with …plot (X,Y) creates a 2-D line plot of the data in Y versus the corresponding values in X. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.assignin (ws,var,val) assigns the value val to the variable var in the workspace ws. For example, assignin ('base','x',42) assigns the value 42 to the variable x in the MATLAB ® base workspace. If val requires evaluation, MATLAB evaluates it in the function that calls assignin, not in the workspace specified by ws.Apr 14, 2014 · Equality of Two Vectors. Create two vectors containing both real and imaginary numbers, then compare the vectors for equality. A = [1+i 3 2 4+i]; B = [1 3+i 2 4+i]; A == B. ans = 1x4 logical array 0 0 1 1. The eq function tests both real and imaginary parts for equality, and returns logical 1 ( true) only where both parts are equal. Description. trueis shorthand for logical(1). true(n)is an n-by-nmatrix of logical ones. true(m,n)or true([m,n])is an m-by-nmatrix of logical ones. true(m,n,p,...)or true([m n p ...])is an m-by-n-by-p-by-...array of logical ones. true(size(A))is an array of logical ones that is the same size as array A. Remarks.Short-circuit expressions are useful in if statements when you want multiple conditions to be true. The conditions can build on one another in such a way that it only makes sense to evaluate the second expression if the first expression is true. Specify an if statement that executes only when S contains an empty field named 'Format'.

An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks are optional.

Functions that access the current non-lexical workspace (this is very rare) will therefore not work as expected. For example, matlab.truth = 42, matlab.exist('truth') will not find the truth variable. Use matlab.evalin('base', "exist('truth')", nargout=1) instead in this case.Description. ypred = predict (mdl,Xnew) returns the predicted response values of the linear regression model mdl to the points in Xnew. [ypred,yci] = predict (mdl,Xnew) also returns confidence intervals for the responses at Xnew. [ypred,yci] = predict (mdl,Xnew,Name,Value) specifies additional options using one or more name-value pair arguments.If you specify X as an array of integer data type, then the value 0 corresponds to the first color in the colormap map.For a colormap containing c colors, values of image X are clipped to the range [0, c-1].. If you specify X as an array of data type single or double, then the value 1 corresponds to the first color in the colormap.

This is a design choice on the part of The MathWorks and fits with most other programming languages: 0 and 1 from any type are commonly used for true and false. ( uint8(1) == 1 also returns true - values, not the class, are compared.)When the input argument is a string array, the double function treats each element as the representation of a floating-point value. However, when the input is a character array, double instead converts each character to a number representing its Unicode® value. As an alternative, use the str2double function.str2double is suitable when the input argument …Cumulative Distribution Function. The cumulative distribution function (cdf) of the Weibull distribution is. p = F ( x | a, b) = ∫ 0 x b a − b t b − 1 e − ( t a) b d t = 1 − e − ( x a) b.

The cumulative distribution function (cdf) of the Weibull distribution is. p = F ( x | a, b) = ∫ 0 x b a − b t b − 1 e − ( t a) b d t = 1 − e − ( x a) b. The result p is the probability that a single observation from a Weibull distribution with parameters a and b falls in the interval [0 x ].An evaluated expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). Otherwise, the expression is false. There are no casts, array operations, or magic involved.Description. while expression, statements, end evaluates an expression , and repeats the execution of a group of statements in a loop while the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false.When you execute find with a relational operation like X>1, it is important to remember that the result of the relational operation is a logical matrix of ones and zeros. For example, the command [row,col,v] = find (X>1) returns a column vector of logical 1 ( true ) values for v.

If pat is an array containing multiple patterns, then startsWith returns 1 if it finds that str starts with any element of pat. TF = startsWith (str,pat,'IgnoreCase',true) ignores case when determining if str starts with pat.This MATLAB function returns the X and Y coordinates of an ROC curve for a vector of classifier predictions, scores, given true class labels, labels, and the positive class label, posclass. The im2gray function converts RGB values to grayscale values by forming a weighted sum of the R, G, and B components: 0.2989 * R + 0.5870 * G + 0.1140 * B. These are the same weights used by the rgb2ntsc (Image Processing Toolbox) function to compute the Y component. The coefficients used to calculate grayscale values in the im2gray function ...‘5’ (the default) for MATLAB 5 and up (to 7.2), ‘4’ for MATLAB 4 .mat files. long_field_names bool, optional. False (the default) - maximum field name length in a structure is 31 characters which is the documented maximum length. True - maximum field name length in a structure is 63 characters which works for MATLAB 7.6+.Boolean numbers are either "TRUE" or "FALSE", represented in MATLAB by a 1 and a 0 respectively. Boolean variables in MATLAB are actually interchangable with …A >= B returns a logical array or a table of logical values with elements set to logical 1 ( true) where A is greater than or equal to B; otherwise, the element is logical 0 ( false ). The test compares only the real part of numeric arrays. ge returns logical 0 ( false) where A or B have NaN or undefined categorical elements.Description. false is shorthand for the logical value 0. F = false (n) is an n -by- n array of logical zeros. F = false (sz) is an array of logical zeros where the size vector, sz , defines size (F). For example, false ( [2 3]) returns a 2-by-3 array of logical zeros. ….

As a simplified example, consider the following function:MATLAB ® represents Boolean data using the logical data type. This data type represents true and false states using the numbers 1 and 0, respectively.Certain MATLAB functions and operators return logical values to indicate fulfillment of a condition. You can use those logical values to index into an array or execute conditional code.
