MATLAB: Matlab to C code conversion issue

functionMATLABmatlab codermatlab function

function final_seq=myapp(x,y,a,b,i,j,z,k,p,m,new,xt,J,ix,X1,final_seq)
x=input(' Enter fast clock ratio '); %fast clock
y=input(' Enter slow clock ratio '); %slow clock
…………….
end
when i try to compile the above code in matlab coder,following error pops up:
" input is not supported for code generation"
What is the work around this issues.Please help its urgent

There is unfortunately no code generation support for the input function as of MATLAB R2019a. We've made an internal note of your request so we can look at lifting that limitation in the future.
In the interim, here is a potential workaround -
function y = foo
    y = input_codegen('Enter a number: ');
    fprintf('Read: %s\n',y);
end
function resp = input_codegen(prompt)
    %#codegen
    coder.extrinsic('input');
    if coder.target('MEX') || coder.target('MATLAB') || coder.target('Sfun')
        resp = input(prompt, 's');
    else
        coder.cinclude('<stdio.h>');
        fprintf('%s',prompt);
        cresp = char(zeros(1,1024));
        coder.ceval('fgets',coder.ref(cresp(1)), 1023, coder.opaque('FILE*','stdin'));
        % Call strlen in C and trim output
        slen = int32(1);
        slen = coder.ceval('strlen',coder.rref(cresp(1)));
        resp = cresp(1:slen);
    end
end
