B = reshape(A, n, m) CS 1173: MATLAB reshape function The reshape function returns a new array with n rows and m columns (n*m must equal the number of elements in the original array). The new array has the same elements as the original. reshaped array array to reshape # of columns in result # of rows in result Reshaping strategy: find the linear representation and re‐ cut based on the number of rows in the reshaped array. Example 1: Different ways to apply reshape to array A A = [1, 2, 3; 4, 5, 6]; B = reshape(A, 3, 2); C = reshape(A, 2, 3); A= A(:) = B = reshape(A, 3, 2) recut B= C = reshape(A, 2, 3) recut C=
