# Is it possible to create a transpose of a matrix by using only one 2D array(input array)?

I was thinking of making either changes in the input matrix or using another temporary matrix to copy data and to delete the input matrix (if this is possible). I am not really sure what we should do I'm just curious.

of course you can if the matrix is a square matrix.

0

but I want use just one matrix

0

you can.

can you write a code I mean the sample

thanks you very much
