title: Matlab - Trying to use vectors with grid coordinates and value at each point for a color plot
body: <p>I'm trying to make a color plot in matlab using output data from another program. What I have are 3 vectors indicating the x-position, y-yposition (both in milliarcseconds, since this represents an image of the surroundings of a black hole), and value (which will be assigned a color) of every point in the desired image. I apparently can't use pcolor, because the values which indicate the color of each "pixel" are not in a matrix, and I don't know a way other than meshgrid to create a matrix out of the vectors, which didn't work due to the size of the vectors.</p>
  
  <p>Thanks in advance for any help, I may not be able to reply immediately.</p>
