MTM

 gt
 element-wise greater than comparison

 Calling Sequence gt(M1,M2)

Parameters

 M1 - matrix, vector, array or scalar M2 - matrix, vector, array or scalar

Description

 • The command gt(M1,M2) performs an element-wise comparison of M1 and M2.
 • For matrices M1 and M2, the result R is a matrix where  R[i,j] = 1, if M1[i,j] > M2[i,j], and R[i,j] = 0 otherwise.
 • For matrix M1 and scalar M2, the result R is a matrix where  R[i,j] = 1, if M1[i,j] > M2, and R[i,j] = 0 otherwise.
 • For scalar M1 and matrix M2, the result R is a matrix where  R[i,j] = 1, if M1> M2[i,j], and R[i,j] = 0 otherwise.
 • For scalars M1 and M2, the result R = 1, if M1 > M2, and R = 0 otherwise.
 • M1 and M2 must be the same size, or scalars.
