Presentation Transcript

  1. COMP 116: Introduction to Scientific Programming Lecture 18: Nested loops and review

  2. Quiz 4 function

  3. Nested loops: what does this code do? % Assume A and B are pre-assigned % matrices and of the same size C=zeros(size(A)); for i=1:size(A,1) for j=1:size(A,2) C(i,j)=A(i,j)*B(i,j) end end

  4. Exercise • Write a function that • given two matrices • returns their product (matrix multiplication not element-wise multiplication) • Use nested for loops • For the first version of the code you can assume that the input matrices are the right size • For the final version, make no such assumption
