I tried to convert my matlab code to a code , but few functions like "fine and eign "(fourier inverse transform and eigen values) are not converting and showing some errors. Hz i could proceed? thanks

Are you using MATLAB Coder?
When you say "fine", do you mean the numeric discrete fourier inverse transform, ifft(), or do you mean the continuous fourier inverse transform ifourier() of the Symbolic Toolbox? Nothing in the Symbolic Toolbox can be compiled.
There is no function named "eign" in MATLAB. Are you referring to the numeric full-matrix routine eig(), the numeric sparse-matrix-compatible routine eigs(), or to the Symbolic Toolbox symbolic routine eig() ?
What error messages are being shown?

"The function 'norminv' is not supported for standalone code generation. See the documentation for coder.extrinsic to learn how you can use this function in simulation."
this is the error is showing while im using "norminv" or "eigs".

norminv() has nothing to do with fourier transforms, but anyhow.
"standalone code generation" implies that you are using MATLAB Coder rather than MATLAB Compiler; Coder has many more restrictions. Both norminv() and eigs() are supported by MATLAB Compiler, at least in current versions.
The Stats Toolbox (norminv) is not supported for MATLAB Coder, at all. http://www.mathworks.com/products/matlab-coder/description2.html
eigs is not supported for MATLAB Coder . http://www.mathworks.com/help/toolbox/eml/ug/bq1h2z7-11.html
eigs is primarily for sparse matrices, but sparse matrices are not supported for MATLAB Coder and MathWorks has not supplied an equivalent to eigs to work on full matrices.
