MTM

 ElementwiseOr
 element-wise logical or Calling Sequence ElementwiseOr(M1,M2) Parameters

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

 • The command ElementwiseOr(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 either M1[i,j] or M2[i,j] is non-zero, and R[i,j] = 0 otherwise.
 • For matrix M1 and scalar M2, the result R is a matrix where  R[i,j] = 1, if either M1[i,j] or M2 is non-zero, and R[i,j] = 0 otherwise.
 • For scalar M1 and matrix M2, the result R is a matrix where  R[i,j] = 1, if either M1 or M2[i,j] is non-zero, and R[i,j] = 0 otherwise.
 • For scalars M1 and M2, the result R = 1, if either M1 or M2 is non-zero, R = 0 otherwise.
 • M1 and M2 must be the same size, or scalars. Examples
