Color map and shading interp not working with plot3

I am using the matlab function plot3 to plot in 3D space. I am using a matrix called x_new, a vector called T_disc and a matrix called all_out. Essentially, the x_new matrix is the discretised x-axis, however each vector within it has been multiplied by a different constant (hence why its a matrix). T_disc is the discretised t-axis, whilst all_out is the output data.

My problem is, when I try to plot this with either shading interp on some kind of color map, like this

plot3(x_new,T_disc,all_out);
shading interp 

It just produces the plot in the image attached (See IMAGE ATTACHED). I would like this image to show a heat distribution just like shading interp would do.

Any thoughts?

surf(x_new,T_disc,all_out);
shading interp 

Shading interp works with pcolor/ surf.

I see, however surf does not take 2 matrices and a vector as input, and therefore I can't use it for my problem.

Why not? Convert your vector into matrix using repmat. And then use surf.

Thank you very much. My problem was that I had some matrix dimensions mixed up. I infact did not have to convert my vector in to a matrix; your original answer was the correct one.
