How to print a variable in matlab

Printing values to the command window. how does one print a value of a variable to the command window? You got it backwards. Typing the variable name first and then running the code will likely get you a "variable name not defined" error message.

Numeric conversions print only the real component of complex numbers. If you specify a conversion that does not fit the data, such as a text conversion for a numeric value, MATLAB ® overrides the specified conversion, and uses %e. Example: '%s' converts pi to 3.141593e+00.function dispwithname (varargin) % DISPWITHNAME (X) -- Display scalar variable (s) in argument list with name (s) for i=1:nargin. disp ( [inputname (i) '= ' num2str (varargin {i})]) end. Alternatively, you could capture the list of desired variables from who with an argument list including appropriate wildcard and then iterate over that list ...fprintf ('The highest point of the mountain is : %d feet.\n', hp); Just like with the C language, if you're familiar with that. Or, if hp is a floating point number instead of an integer, use %f instead of %d: fprintf ('The highest point of the mountain is : %.2f feet.\n', hp); That is the correct behavior.print in a loop .

D = sprintf ('%10e',A) Honestly, I don't think any of these ways are any easier to deal with for whatever are your purposes. But whatever floats your boat.@HansHirse's answer is excellent. Another alternative using repmat below. Could have compacted the code a bit but left in its current form for accessibility. ** Alternative Approach: ** repmatYou can do that using a regular table but you cannot use ‘f(x)’ as a variable name because it is not a valid MATLAB variable name. ... To do it without the table functions, you would have to use a couple of fprintf statements to print it to the Command Window: Data = [ 2 1 -0.307799 0.00. 3 0.544459 0.0153522 0.01 ...With respect to getting ans = 3 as an output, it is probably because you are not assigning the output from answer to a variable. If you want to get all of the output values, you will have to call answer in the following way: [out1,out2,out3] = answer(1,2); This will place the value d in out1, the value e in out2, and the value f in out3.When you do the following:Learn more about fprintf using a variable MATLAB I set this varaible number first thing at the top of the scrip.

If you add a title or subtitle to an axes object, then the font size property for the axes …The other option is to save your results in a matrix, as you did, and then wait to print until the end. In fprintf, you are just printing to a destination, rather than saving the string to use later. In that case, use fprintf when you are ready to print that section of your work.I have two files with similar data and I want to extract them into a file, and I also want to print the same line for the same data in the two files Please help me F1 = fopen( 'E.txt' );Select a Web Site.

example. T = table ('Size',sz,'VariableTypes',varTypes) creates a table and preallocates space for the variables that have data types you specify. sz is a two-element numeric array, where sz (1) specifies the number of rows and sz (2) specifies the number of variables. varTypes specifies the data types of the variables. example.The data type (class) must be a built-in MATLAB ® numeric type. For other classes, the static rand method is not invoked. For example, rand(sz,'myclass') does not invoke myclass.rand(sz). Size arguments must have a fixed size. See Variable-Sizing Restrictions for Code Generation of Toolbox Functions (MATLAB Coder).s = summary (T) returns a structure, s, that contains a summary of the input table or timetable. Each field of s is itself a structure that summarizes the values in the corresponding variable of T.

To create a new variable, enter the variable name in the Command Window, followed by an equal sign ( =) and the value you want to assign to the variable. For example, if you run these statements, MATLAB adds the four variables x, A , I, and C to the workspace: x = 5.71; A = [1 2 3; 4 5 6; 7 8 9]; I = besseli (x,A); C = {A A A}; s = struct (field,value) creates a structure array with the specified field and value. The value input argument can be any data type, such as a numeric, logical, character, or cell array. If value is not a cell array, or if value is a scalar cell array, then s is a scalar structure. For instance, s = struct ('a', [1 2 3]) creates a 1-by-1 ...You can use the CHAR method for symbolic objects to convert them to strings and the FPRINTF function to print the strings to the screen.
