• diag — diagonal including or extracting
• eye — identity matrix
• ind2sub — linear index to matrix subscript values
• linspace — linearly spaced vector
• logspace — logarithmically spaced vector
• meshgrid — create matrices or 3-D arrays
• ndgrid — arrays for multidimensional function evaluation on grid
• ones — matrix made of ones
• rand — Random numbers
• squarewave — generates a square wave with period 2*%pi
• sub2ind — matrix subscript values to linear index
• testmatrix — generate special matrices, such as Hilbert, Franck
• toeplitz — Toeplitz matrix
• zeros — matrix made of zeros
