For example, consider a MAT-file with variables height, width, and length. If you load these variables in a function such as findVolume, MATLAB interprets the reference to length as a call to the MATLAB length function, and returns an error. function vol = findVolume(myfile) load(myfile); vol = height * width * length; end. Error using length Not enough input arguments.
