a Simple Matrix question

if i have two

matrix_A = [ 200 201 130 150 202 203]

Matrix_B = [ 255 255 130 150 255 255]

how can i create Matrix_C such that

1) if the element inside Matrix_A and Matrix_B is identical it will display 255 in Matrix_C

2) and if they are not identical, it will display Matrix_A element

Ideal Matrix_C = [ 200 201 255 255 202 203]

Answer 1

Matrix_C  = matrix_A; 
matrix_C(ismember(matrix_A, Matrix_B)) = 255;

Hello LC

Matrix_C = matrix_A;
Matrix_C(matrix_A == Matrix_B) = 255;
