This type of function must be defined within a file, not at the command line. Often, you store a function in its own file. In that case, the best practice is to use the same name for the function and the file (in this example, fact.m), since MATLAB ® associates the program with the file name. Save the file either in the current folder or in a ...

In a function file which contains only function definitions. The name of the file must match the name of the first function in the file. In a script file which contains commands and function definitions. Script files cannot have the same name as a function in the file.

That is, when you call a function or method within a program file, MATLAB checks whether the function is a local function before looking for other main functions. Therefore, you can create an alternate version of a particular function while retaining the original in another file.

Function files can be MATLAB code (.m), Live Code file format (.mlx), MEX functions (platform dependent extensions), and P-code files (.p). The base name of the file must be a valid MATLAB function name. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores.

If you do not specify filename, the load function searches for a file named matlab.mat. If filename has no extension (that is, does not end with a period followed by text), load searches for a file whose name is filename with .mat appended to it.

Read the file using fread before calling an I/O function, such as fseek or frewind, that sets the file position indicator. Thread-Based Environment Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool .

If you do not specify filename, the save function saves to a file named matlab.mat. If filename has no extension (that is, does not end with a period followed by text), and the value of fmt is not specified, then the save function appends .mat to filename .

If the File name-value argument is empty, then MATLAB function returns an anonymous function. If a symbolic expression involves a conditional statement, such as a piecewise condition, matlabFunction can convert the expression to a MATLAB file, but not an anonymous function. The function in the generated file can accept only scalar inputs.

Feb 27, 2012 · In new enough versions of MATLAB, inside a function, if you call a function and you then assign to a variable with the same name as the function, and you then use that name, then MATLAB will know that the function is out of scope (because the variable has that name), but it will also have locked-in the idea that the name is a function rather than a variable.

Data from the file, returned as a matrix, multidimensional array, or scalar structure array, depending on the characteristics of the file. Based on the file format of the input file, importdata calls a helper function to read the data. When the helper function returns more than one nonempty output, importdata combines the outputs into a struct ...
