Matlab M-file to generate the transpose of a matrix by using” for…end” loops to implement the transpose
Can anyone help me out with this Matlab code?
I need to write a M-file to generate the transpose of a matrix by using “for…end” loops to implement the transpose. Thanks
The easiest (and most inefficient!) way to do this:
function At = transpose(A)
% Returns the transpose of A
% 1) Number of rows and columns
[nr,nc] = size(A)
% 2) Allocate the matrix:
At = zeros(nc,nr) % notice the change row->column
% 3) Loop through the numbers
for i = 1:nr
for j = 1:nc
At[j,i] = A[i,j]
end
end
% End of m-file
The transpose of a matrix is nothing but exchanging rows for columns and vice versa.
Of course, Matlab has a command for computing the transpose in an efficient manner; that command is ” ‘ ” (the apostrophe), so if you want Bt to be the transpose of B, just type in Matlab:
>> Bt = B’
And that’s it.
I wonder… why did they ask you to do this in such an inefficient manner?
