Hi, I have written a module using Principal component analysis (PCA) .Input to my code is (1000x7) values. Now I want to convert my Matlab code into a c code or c++ code. I’m having Matlab functions like eigs (which I’m using to get Eigen value and Eigen vector), norminv in my code. When I’m trying to convert my Matlab codes to c code, i’m getting an error saying that Matlab cannot convert these functions (eigs, normniv) to equivalent c code and asked to make those functions as a extrinsic function. I tried to write a separate c code for Eigen values and Eigen vectors but since my input matrix is a non-symmetric matrix i can’t write a code, even i go through Numerical Recipes in C book they are saying that we can write a code only to a symmetric matrix.

Please anybody help me to solve this prob. Thanks in advance.

Just to make sure we know what you are doing: do you use MATLAB Coder for conversion to C (or Embedded MATLAB/Real-Time Workshop, if you are using a pre-R2011a version)?
