Matlab中本身有Q函数，即qfunc() 其 反函数是qfuncinv()help qfuncinv qfuncinv Inverse Q function Syntax y = qfuncinv(x)Description y = qfuncinv(x) returns the argument of the Q function at which the Q function's value is x. The input x must be a real array with elements betwee...
In Matlab, the Inverse function is obtained by applying the ‘ finverse ’ command. This command returns the value of the given function variable. In finverse f stands for function and after finverse, there will be parameters or argument list inside the brackets depending upon the requirement. i...

摘要:Matlab的命令里只有QR分解,如何求QL分解和LQ,RQ分解?LQ分解: [Q 1,R 1]= qr (H'); H=(Q 1*R 1)'=R 1' *Q 1'=L*Q; 所以下三角阵L=R 1',正交阵Q=Q 1'QL分解:[Q 1,R 1]= qr ( inv(H' ) ); H'=(Q 1 阅读全文 ...
