load (MATLAB Functions)
matlab.izmiran.ru › help › techdocload loads all the variables from the MAT-file matlab.mat, if it exists, and returns an error if it doesn't exist. load ('filename') loads all the variables from filename given a full pathname or a MATLABPATH relative partial pathname. If filename has no extension, load looks for a file named filename.mat and treats it as a binary MAT-file.
