A colormap is a matrix of values that define the colors for graphics objects such as surface, image, and patch objects. MATLAB draws the objects by mapping data values to colors in the colormap. Dozens of different colormap color maps are preset in Matlab, as shown in Fig:今天的分享就到...
well... i tried to use both answers and the realiza same thing: figure divided in color by the numbers in matrix. instead i want to know how to have a picture(jpg for intend) that is my matrix if A=[1 2 3;4 5 6;7 8 9]; i want to realize a way to picture a matrix with...

i saved a 3d image to my current folder using the expression hgsave(gcf, 'Image3D.fig', '-v7.3'); i wish to import the image again to my work space as M*N*O MATRIX.i tryied import to work space but i got 5 variables named children,handle,special,type,properties...

or a matrix of equal size. If the input is a matrix, polarplot plots the columns of rho against the columns of theta. It is also possible to have one input as a vector and the other as a matrix, but the length of the vector must be equal to one of the dimensions of the matrix...
pcolor(C) creates a pseudocolor plot using the values in matrix C. A pseudocolor plot displays matrix data as an array of colored cells (known as faces). MATLAB® creates this plot as a flat surface in the x-y plane. The surface is defined by a grid of x- and y-coordinates that...
