You've got three variables but what do you mean by the second table? What's the row name and column name?

Hi, the row is "DIRECTION" and the column is "FREQUENCY". I want to plot a matrix FREQUENCY x DIRECTION. Each (FREQUENCY, DIRECTION) has a value (ENERGY DENSITY=2nd column).
Thanks

Use griddata, probably something like this:
[yq,xq] = ndgrid(0:0.1:2,0:60:360);
vq = griddata(x,y,v,xq,yq);
