MTM

 ne
 non-equivalence of array entries

 Calling Sequence ne(M1,M2)

Parameters

 M1 - array or scalar M2 - array or scalar

Description

 • The ne(M1,M2) command tests if the elements of M1 and M2 are not equal.  The result is an integer array with 1's where M1[i] is not equal to M2[i], and 0's where the entries are equal.
 • M1 and M2 must be the same size, or scalars.  If M1 is an array and M2 is a scalar, the result will be an array the same size as M1, with 0 and 1 entries indicating entries that were not equal to the scalar value M2.

 > $\mathrm{M2}≔\mathrm{Matrix}\left(\left[\left[1,2\right],\left[3,5\right]\right]\right):$
 > $\mathrm{ne}\left(\mathrm{M1},\mathrm{M2}\right)$
 $\left[\begin{array}{cc}{0}& {0}\\ {0}& {1}\end{array}\right]$ (1)
