I got the data in 3 vectors like this:

X Y Intensity

0 1 4

0 2 3

1 0 9

etc

I want to interpolate between the points, to have a continuous plot.

I just need to know the name of that kind of plot please or the name of the command in Matlab, I'll do the code myself.

Thank you very much!

From the data you presented, I would use scatteredInterpolant class.

Hello,

I already did it, thanks!

I didn't need to interpolate because contour does it by itself!

Now i wanted to do a legend like assigning the value of the intensity to a color, can you give me any tips regarding that??

Thanks!

My pleasure!

The colour legend won’t look like the one in your Question, but the functions you want are colorbar and colormap.
