The EXP function applies the exponential function to every element of the argument matrix. The exponential is the natural number e raised to the indicated power. For example, the following statements compute the exponentials of several numbers:
b = {1 2 3 4}; a = exp(b); print a;
If you want to compute the exponential of a matrix, you can call the EXPMATRIX function in the IMLMLIB module library.
