plotSurface

Purpose

Graphs a 3-D surface.

Format

plotSurface([myPlot, ]x, y, z)
Parameters:
  • myPlot (struct) – Optional argument, a plotControl structure.
  • x (1xK vector) – the x-axis data.
  • y (Nx1 vector) – the y-axis data.
  • z (NxK matrix) – the matrix of height data to be plotted.

Examples

// Clear out variables in GAUSS workspace
new;

// Create contour data
x = seqa(-4, 0.1, 50)';
y = x';
z = sin(y) .* cos(x) ;

// Set up control structure with defaults
// for surface plots
struct plotControl myPlot;
myPlot = plotGetDefaults("surface");

// Set color map
plotSetColormap(&myPlot, "plasma");

// Draw graph using plotcontrol structure
plotSurface(myPlot, x, y, z);
