MATLAB: Plotting a surface with scatter data

Question

I have density which is a 310×1 matrix. I have pressure which is a 310×41 matrix. Each column corresponds to a different temperature and each row from 1 to 310 just corresponds to the pressure at a given density in the density matrix.

The temperature is stored in temperature variable as a 1×41 matrix that goes from 100 to 300 in increments of 5 K. How can I plot this data as a surface?

If I try:

surfc(density,temperature,pressure)

I get that the data dimensions must agree.

I have my x-data, density as 310×1.

I have my y-data, temperature as 1×41

Then my z-data, pressure, is 310×41.

Why do the dimensions not agree?

I think I know the issue, but can I just tell MATLAB that x and y values do not change for each matrix? If I manually create every column with all the repetitive data it works. I am not sure if I am being clear here or not, but I imagine the way I am going about doing it is not the most efficient.

Answer 1

[D,T]=meshgrid(density,temperature);
surf(D,T,pressure);
