In general, we may define multiplication of a matrix by a scalar as follows: If A = [a ij] m n is a matrix and k is a scalar, then kA is another matrix which is obtained by multiplying each element of A by the scalar k. In other words, kA = k [a ij] mn = [k (a ij )] mn, that is, (i, j) th element of kA is ka ij for all possible values of . Calculate with arrays that have more rows than fit in memory. I want to multiply each atom with a 49 different scalar value. Multiplication of a matrix by a scalar is also defined elementwise, just as for vectors.
