A simple 3D plot of a matrix

Dear All I have a matrix (74x3). The first and second columns are X and Y coordinates [-270 :270]. The third column is the intensity of each X, Y cooridnates. I want to plot the X values on x-axis, Y on y-axis and the intensity on z-axis as a surface or mesh. how can it be done? Thanks in advance

Thanks Doug. Do you know if it possible to show the intensity value on the plot in stead of colorbar?
