Chained matrix multiplication in c

WebThe straightforward multiplication of a matrix that is X × Y by a matrix that is Y × Z requires XYZ ordinary multiplications and X(Y − 1)Z ordinary additions. In this context, it is typical to use the number of ordinary multiplications as a measure of the runtime complexity. If A is a 10 × 30 matrix, B is a 30 × 5 matrix, and C is a 5 × ... WebMar 29, 2015 · The crux of the problem is we are basically trying to 'parenthesise' i.e. prioritize how we chain our matrices so that they are multiplied most efficiently and it's reflected in this line of code: q = m [i,k] + m [k+1,j] + p [i-1]*p [k]*p [j];
