Purpose Test matrices<br />

Syntax [A,B,C,...] = gallery('tmfun',P1,P2,...)<br />

gallery(3) a badly conditioned 3-by-3 matrix<br />

gallery(5) an interesting eigenvalue problem<br />

gallery<br />

Description [A,B,C,...] = gallery('tmfun',P1,P2,...) returns the test matrices<br />

specified by string tmfun. tmfun is the name of a matrix family selected from<br />

the table below. P1, P2,... are input parameters required by the individual<br />

matrix family. The number of optional parameters P1,P2,... used in the<br />

calling syntax varies from matrix to matrix.The exact calling syntaxes are<br />

detailed in the individual matrix descriptions below.<br />

The gallery holds over fifty different test matrix functions useful for testing<br />

algorithms and other purposes.<br />
