view — Control 3-D camera angles for surfaces and spatial plots using azimuth/elevation views and MATLAB view semantics.

view reads or updates the camera orientation for the current axes or an explicit axes handle. In RunMat it stores subplot-local azimuth and elevation state, supports MATLAB view(2), view(3), view([az el]), and view(az, el) call forms, and integrates with the same handle/property system used by get and set.

How view works in RunMat

• view with no angle arguments queries the current [az el] pair.
• view(2) selects the standard top-down 2-D camera and view(3) restores the standard 3-D camera preset.
• Explicit azimuth/elevation values can be passed as two scalars or as a two-element vector.
• View state is subplot-local and does not leak across different axes in a subplot grid.
• Axes handles can be passed explicitly so camera changes target a specific subplot rather than whichever axes happens to be current.

Examples

Set an explicit 3-D camera angle

[X, Y] = meshgrid(linspace(-2, 2, 60), linspace(-2, 2, 60));
Z = sin(X.^2 + Y.^2);
surf(X, Y, Z);
view(45, 30);

Use MATLAB-style view presets

[X, Y] = meshgrid(linspace(-3, 3, 40), linspace(-3, 3, 40));
Z = sin(X) .* cos(Y);
surf(X, Y, Z);
view(2);
view(3);

Query a subplot-local camera

ax = subplot(1, 2, 2);
plot3(cos(0:0.1:5), sin(0:0.1:5), 0:0.1:5);
view(ax, [60 20]);
get(ax, 'View')

Expected output:

% Returns a 1x2 vector [60 20]
