I use matlab coder (matlab version:R2017a) to compile matlab code to C code .And I want to use single floating-point number.While I have used filtfilt function in matlab code. Then I got an error it said filtfilt only takes double floating-point number.I have tried using single() to convert parameters in filtfilt but still failed.Is there anyone can help me?Thanks.

Either convert the signal using double(), or use FEX: FilterM, which accepts single values, but accumulate the internal filter state as doubles to increase the accuracy or the output.

While filter works on single also, filtfilt accepts doubles only (at least in some Matlab versions). You can either include the C-Mex FilterX and FiltFiltM.m (see https://www.mathworks.com/matlabcentral/answers/48620-generating-c-c-code-from-m-function-include-mex-file), or modify the builtin filtfilt.m function to accept singles also. I still do not see, where the problem is.
