An error occurs if you try to combine two matrices that have different number of rows. ##You can use Matrix Answer Memory to assign the results of the above matrix input and edit operations to a matrix variable. To do so, use the following syntax. Fill (n,Mat@)MatA Augment (Mat@, MatA)MatBIn the above,@,A, and B are any variable names A through Z, and n is any value. The above does not affect the contents of Matrix Answer Memory.
