Scalar multiplication: to multiply a matrix A by a scalar r, one multiplies each entry of A by r. Zero matrix O: all entries are zeros. Negative: A is defined as (1)A. Subtraction: A B is defined as A + (B). As far as the linear operations are concerned, the m×n matrices ...

we can see that for every element, our function computes an intermediate 1x1 matrix and then gets its value out. Instead, we can simply use an accumulator and avoid the memory allocation, as follows: In [1]: # Standard matrix multiplication algorithm.functionmult{T}(x::Matrix{T},y::Matri...
