对于较低版本的matlab库中，缺少归一化的函数mapminmax.m 包含（它的子函数boiler_process.m），它是libsvm-mat需要用到的函数。-With earlier versions of matlab library, the lack of normalized functions mapminmax.m contains (its Functions boiler_process.m), it is libsvm-mat need to use the funct

matlab的mapminmax函数,boiler_process.m函数princomp函数，在fratuto推出的libsvm中用到的三个函数，在使用libsvm中没有它总是报错- -The mapminmax matlab function (projection map)
