absmax

Returns the value of the element with the largest absolute value in the input matrix.

Returns the value of the element with the largest abs value in the input matrix 'A'. Input 'A' must be numeric, but can be any size and shape.

This is useful because it eliminates iterating through all the dimensions of a matrix.

examples:
A=[-5 3 2 3; 3 2 1 4];
absmax(A) will return -5

A=[643,10];
absmax(A) will return 643
