Section: Inspection Functions
Returns information on a function (if defined). The usage is
which(fname)
where fname is a string argument that contains the name of the function. For functions and scripts defined via .m files, the which command returns the location of the source file:
y = which(fname)
will return the filename for the .m file corresponding to the given function, and an empty string otherwise.
First, we apply the which command to a built in function.
--> which fft Function fft is a built in function
Next, we apply it to a function defined via a .m file.
--> which fliplr Function fliplr, M-File function in file '/home/sbasu/Devel/FreeMat4/toolbox/array/fliplr.m'
