How can I print row number to matrix in matlab?

How can I print row number to matrix in matlab?

I have a matrix and I want to print the row number on the cells that write 1 in this matrix. How can I do it?

Maybe it will be clearer if I explain with an example.

first row 1 0 1

second row 0 0 1

third row 1 1 0

fourth row 0 1 1

This is my matrix. I want to convert this matrix to this with code:

first row 1 0 1

second row 0 0 2

third row 3 3 0

fourth row 0 4 4

The values of 1 in the second row got the value 2 because they were in the second row, those in the third row got the value 3. 0 values remained the same. How can I do this in a large matrix?

thank u

The question is not clear yet. Numerical matrices have "elements". "Cells" are found in cell arrays.

If your matrix is:

M = rand(2, 3)

what is the wanted result?

Answer 1

M=randi(2,10,3)-1;%sample matrix
newM=M.*(1:size(M,1))';

This answer is correct. Thank u so much

Answer 2

[Stephen23]

M = [1  0  1;  0  0  1; 1  1  0; 0  1  1]

M = 4×3

1 0 1 0 0 1 1 1 0 0 1 1

V = 1:size(M,1);
Z = V(:).*M

Z = 4×3

1 0 1 0 0 2 3 3 0 0 4 4
