Converting a three-column set of data to xyf matrix suitable for a contour plot
I have a set of data (the output of a CFD calculation) that consists of three columns x and y showing location and a third column that we call f which contains the values of the variable calculated for every specific xy location. I want to convert this array to a 2D matrix where x and y are now in the horizontal and vertical directions. Some data points simply do not exist because they are outside of the domain boundaries.
So basically, what I need to do is this (where the black cells are the ones for which the original dataset has no values.):I have a set of data (the output of a CFD calculation) that consists of three columns x and y showing location and a third column that we call f which contains the values of the variable calculated for every specific xy location.
