Undefined function 'function_name' for input arguments of type 'double'

I'm solving a convex optimization problem(for matrix) in which I'm using 2 functions, one for objective function and another for nonlinear constraint. When I run it via optimization toolbox, it shows "Undefined function 'f_name' for input arguments of type 'double'".Also, I passed the initial value of x as zero matrix of required size(which is 498 here). Is the starting value passed correctly?
Here is the function codes
function f= coheren(x)
load ('Dictionary.mat','D');
Z = (D)*(D');
[V, U,W]=svd(Z);
a = mtimes(U,V');
b = mtimes(V,U);
f = (norm(U-(a*(x')*(x)*b)))^2;
end
function [c,ceq] = cohcon(x)
load ('Dictionary.mat','D');
[m,n]= size(D);%size(x)
k = D*(D');
T = (x)*k*(x');
[V1,U1,W1] =svd(T);
ceq = rank(U1)-m;
c= [];
end
