Error using ==> mpower 这样的错误？其实，用 help mpower 查阅该函数的参考信息，可以知道mpower是矩阵幂函数（Matrix power），对应的符号就是“^”，而这个符号在楼主的表达式中。这里，要顺便做一点背景性的介绍：MATLAB中的运算符其实都有对应的函数，例如，“^”对应mpower，“*”对应mtimes，...
clear;clc b=0:0.01:5;x=b;f=1./(((1-x.^2).^2+(2*0.5*x).^2).^0.5); % 还要加“点”plot(x,f)
MATLAB Online에서 열기 Roger, it can happen in floating point arithmetic, though not algebraically. For example, diag(rand(1,5)) raised to a large enough power will underflow to all 0's. For example, A = diag([0.757740130578333, 0.743132468124916, 0.392227019534168, 0.655477890177557, 0.1...
I have a matrix in this form: A=1.0e+05 *[-0.0000 -0.0000 1.5856 -0.0000 ]; And I want to write this matrix in this form: A=[-0.0000 -0.0000 1.5856 -0.0000 ]; Most importantly, matrix is generated randomly. Its power may vary. It may be some other number at every iteration. ...

Doing the calculation (A^(10^10) using repeated squaring and multiplication) in Excel gave 3.05424E-12. I am using MATLAB 2013b on windows 7 64-bit. Why does A^(10^10) fail but (A^(10^9))^10 work? 댓글 수: 1 John D'Errico 2014년 2월 26일 Time to learn about...
