Divides a plot into a grid of subplots and assigns the cell location in which to draw the next created graph.


plotLayout(g_rows, g_cols, ind)
  • g_rows (scalar) – number of rows of the graph layout.

  • g_cols (scalar) – number of columns of the graph layout.

  • ind (scalar) – cell location in which to place the next created graph.


// Create 10x4 matrix where each column is an additive
// sequence from 0.1 to 1.0
x = seqa(0.1, 0.1, 10);
y = ones(10, 4).*x;

// Apply a function to each column of 'y'
y[.,1] = cos(x);
y[.,2] = sin(x);
y[.,3] = cdfn(x);
y[.,4] = exp(x);

for i(1, 4, 1);
   // Divide plot canvas into a 2x2 grid of subplot
   // locations and place each newly created graph in the
   // next available cell location.
   plotLayout(2, 2, i);

   // Plot each column of y in a separate subplot window.
   plotXY(x, y[., i]);

// Clear the layout so the next plot will not be inside this
// layout


After calling this function all subsequent graphs will be plotted inside of the specified layout until the layout is reset with plotLayout(), or the layout is cleared with plotClearLayout().
