MTM[ElementwiseAnd] - element-wise logical and

Calling Sequence

ElementwiseAnd(M1,M2)

Parameters

M1

-

array or scalar

M2

-

array or scalar

Description

• 

The command ElementwiseAnd(M1,M2) performs an element-wise comparison of M1 and M2.

• 

For arrays M1 and M2, the result R is an array where  R[i,j] = 1, if both M1[i,j] and M2[i,j] are non-zero, and R[i,j] = 0 otherwise.

• 

For array M1 and scalar M2, the result R is an array where  R[i,j] = 1, if both M1[i,j] and M2 are non-zero, and R[i,j] = 0 otherwise.

• 

For scalar M1 and array M2, the result R is an array where  R[i,j] = 1, if both M1 and M2[i,j] are non-zero, and R[i,j] = 0 otherwise.

• 

For scalars M1 and M2, the result R = 1, if both M1 and M2 are non-zero, R = 0 otherwise.

• 

M1 and M2 must be the same size, or scalars.
