1-1 Creating Matrice Method 3: Concatenating Matrices Matrix concatenation is the process of joining one or more matrices to make a new matrix. The brackets l operator discussed earlier in this section serves not only as a matrix constructor, but also as the MATLAB concatenation operator The expression C=[AB] horizontally concatenates matrices A and B. The expression C= [A; B] vertically concatenates them1-1 Creating Matrice The expression C = [A B] horizontally concatenates matrices A and B. The expression C = [A; B] vertically concatenates them.
