Plotting 2 Matrices

Hi,

I'm having difficulty constructing a plot. I have two 2D matrices of the same size, matrix one contains elevation data (a cross section of a 3D matrix), matrix two contains attribute data of the same points contained in matrix one. I'm trying to construct a plot that preserves the elevation data and does a color shading based on the attribute values contained in matrix two.

I plot matrix one with using the following: for n = 1:300 plot(matrix one(n,:)) hold on end

This produces a plot with a series of cross sections stacked on top of each other. I'd like to preserve the appearance of this plot while shading it using the values in matrix two. Basically, I want the position of a point to be based on it's value in matrix one and the color based on it's value in matrix two. I hope I've explained this clearly enough. I'd appreciate any help.

Thanks.

You can try

surf(matrix1,matrix2)

and see if that's what you want.

Thanks for the response. I tried your suggestion and it doesn't give me what I'm looking for. To restate what I'm trying to do, I have two matrices, matrix1 contains elevation data. Every row in matrix1 is a cross section of a 3D surface. When I plot matrix one it gives me a bunch of lines, one on top of the other, representing surface elevations at different time steps in the model.

Matrix2 is the same size as matrix1 and contains numerical attribute data for each cell in matrix1. I basically want to plot matrix1 and perform a color shading based on matrix2.

pcolor(matrix2) can do a color shading, but I don't know about the 3D aspect of your problem..
