MATLAB Functions

Create matrix for movie frames

M = moviein(n)
M = moviein(n,h)
M = moviein(n,h,rect)

Description

moviein

allocates an appropriately sized matrix for the getframe function.

M = moviein(n)

creates matrix M having n columns to store n frames of a movie based on the size of the current Axes.

M = moviein(n,h)

specifies a handle for a valid Figure or Axes graphics object on which to base the memory requirement.

M = moviein(n,h,rect)

specifies the rectangular area from which to copy the bitmap, relative to the lower-left corner of the Figure or Axes graphics object identified by h.
rect = [left bottom width height], where left and bottom specify the lower-left corner of the rectangle, and width and height specify the dimensions of the rectangle. Components of rect are in pixel units.

Examples

Use moviein to allocate a matrix for the movie frames and getframe to create the movie:

Z = peaks;
surf(Z); 
M = moviein(20);
% Freeze Axes limits
axis manual
set(gca,'nextplot','replacechildren');
% Record the movie
for j = 1:20 
    surf(sin(2*pi*j/20)*Z,Z)
    M(:,j) = getframe;
end
% Play the movie twenty times
movie(M,20)
