FreeMat supports the vast majority of MATLAB’s features including:.

To place labels on the contour plot, use the clabel function. Furthermore, you can supply an axis to target the contour plot to (so that it does not get added to the current axis, which is the default): contour(axis_handle.)įinally, the contour command returns a handle to the newly returned contour plot. If you have data that lies on a particular X,Y grid, you can pass either vectors x,y or matrices X,Y to the contour function via contour(X,Y,Z)Įach form of contour can optionally take a line spec to indicate the color and linestyle of the contours to draw: contour(.,linespec) If you want to generate a contour for a particular level, you must pass a vector where t is the level you want to contour. For more control, you can provide a vector v containing the levels to contour. Which indicates that you want n contour levels. Alternately, you can specify a scalar n contour(Z,n)

The x,y coordinates of the contour default to 1:n and 1:m, where n is the number of columns and m is the number of rows in the Z matrix. Which generates a contour plot of the data in matrix Z, and will automatically select the contour levels. There are several syntaxes for the command.
