Reapeting same line with different coordinates

Hi, I have a line in matlab with X,Y,Z coordinates. I need to make for example 10 lines with same Y and Z coordinates but with changed X coordinate, where X is the same for the whole line. Is there a code for that or a way to do it?

It's very likely that there is a simple way to do it. However, your input and output description is not very clear. Can you give an example of inputs in valid matlab syntax and the desired output.

for example I have matrix A with 3 columns and 30 rows. for example row 1 is X, row 2 is Y and row 3 is Z, and for are X-s value is 50. and for Y and Z are random numbers. I would like to make matrx B with 3 columns and 30 rows also with X,Y,Z where Y and Z stay the same, and X-s are turned from 50 to 25. Picutre shows you matrix.

If I understood correctly, all you need to do is

B = A;
B(:, 1) = 25;
