badly scaled Matrix?!! Hello, Scilab help states that If a matrix is badly scaled or nearly singular, a warning message will be displayed: "matrix is close to singular or badly scaled." (http://help.scilab.org/docs/5.3.3/en_US/inv.html) What do these terms mean? "well scaled" , "badly scaled" , "nearly singular" Can anyone please give explanation with example to me? Thanks in advance.
