NettetMatrix Multiplication There are exactly two ways of multiplying matrices. The first way is to multiply a matrix with a scalar. This is known as scalar multiplication. The second way is to multiply a matrix with another matrix. That is known as matrix multiplication. Scalar Multiplication Nettet7. mar. 2024 · For example, on this code, after adding 10+20+30+40 = 100 on the first column, the condition multiple of 100 is met. The element corresponding to this point on the second column is 5. Store this number to variable X. Continuing the addition of the first column elements, 10+20+30+40 +5= 105, the condition is not met, nothing happens to X.
