subplot

Create axes in tiled positions.

Syntax

• subplot(m, n, p)
• subplot('mnp')
• subplot('Position', pos)
• ax = subplot(...)

Input argument

• m - Number of grid rows: scalar positive integer.
• n - Number of grid columns: scalar positive integer.
• p - Grid position for new axes: scalar or vector.
• pos - Custom position for new axes: [left bottom width height].

Output argument

• ax - a graphics object: axes type.

Description

subplot(n, m, p) divides the current figure into a 2-dimensional grid.

Each of which can contain a plot of some kind.

Examples

f = figure();
X = linspace(-pi, pi) * 2;
Y1 = cos(X) .* exp(-2 * X);
Y2 = cos(X * 2) .* exp(-2 * X);
Y3 = cos(X * 3) .* exp(-2 * X);
Y4 = cos(X * 4) .* exp(-2 * X);

subplot(4, 1, 1)
plot(X, Y1,'b');
subplot(4, 1, 2)
plot(X, Y2, 'r');
subplot(4, 1, 3);
plot(X, Y3, 'g');
subplot(4, 1, 4);
plot(X, Y4, 'k');

f = figure();
t = 0 : (2 * pi/100) : (2 * pi);
X = cos(t * 2) .* (2 + sin(t * 3) * 0.3);
Y = sin(t * 2) .* (2 + sin(t * 3) * 0.3);
Z = cos(t * 3) * 0.3;
subplot(2, 2, 1)
surf(peaks());
axis equal
view(3)
subplot(2, 2, 2);
plot(t, X);
subplot(2, 2, 3);
plot(t, Y);
subplot(2, 2, 4);
plot(t, Z);
