HDL Coder requires every variable to be unambiguously typed. Your issues all can be traced back to the function fcm being unsupported and/or undefined. This leaves center and member untyped. The rest just cascade from there.

You should also take a look at the Supported Function list for HDL Coder. You are using multiple functions that aren't supported for HDL code generation, such as greythresh and im2bw. See this MATLAB Answer for more information.

use coder.extrinsic('rgb2gray','imshow','figure','filter2') where rgb2gray, imshow,figure, filter2 are matlab function used in your m file.
