Matlab plot 3d matrix.

I have a matrix with dimensions N by 3, for example 100 rows and 3 columns. Each row correspondds to the 3D location of a point, i.e., we have 100 points. I want to pot the 100 points and connect them as a surface.This example shows how to create a variety of 3-D plots in MATLAB®. Mesh Plot. The mesh function creates a wireframe mesh. By default, the color of the mesh is proportional to the surface height. z = peaks(25); figure mesh(z) Surface Plot. The surf function is used to create a 3-D surface plot.So I have a 1024*4 matrix. I want to plot this either on a 3d surface with color as an extra dimension representing signal strength or in something like a volume plot where the sliced up sections are just normal colormaps. ... MATLAB: Need to make a 4D plot (3D + Colour/Color) 1 4D plot display variables with data cursor Matlab.Remember that the data contained in any matrix takes up it's own dimension (Z-axis) or color (surf/mesh). So a 2D matrix needs either: (1) 3 dimension plot (using mesh/surf) or (2) a 2D plot and a colormap. A 3D matrix needs a 3 dimension plot AND a color map, but can still only show slices because it cannot show a volume with different …hi.
