Not enough input arguments for an anonymous function.

I have this anonymous function:

g = @(x,k) exp(cos(x))^k

I am getting this error:

Not enough input arguments.

Error in solution>@(x,k)exp(cos(x))^k (line 5)

g = @(x,k) exp(cos(x))^k

Im not sure the fix for this because x and k are both represented in the function.

[Torsten]

g = @(x,k) exp(cos(x)).^k;
g(2,4)

ans = 0.1893

x and k are both represented in the function, yes, but how are you calling the function? If you call it with fewer than two arguments you'll get that error.

% defining g:
g = @(x,k) exp(cos(x))^k

g = function_handle with value:
    @(x,k)exp(cos(x))^k

% calling g with 2 arguments:
g(pi,2) % ok

ans = 0.1353

% calling g with 1 argument:
g(pi) % error

Not enough input arguments.

Error in solution (line 1)
g = @(x,k) exp(cos(x))^k

You haven't shown how you are calling the function g, so check on that.

I think you probably wanted to raise to the power element-wise, so I changed your function to

g = @(x,k) exp(cos(x)).^k;

But that won't cause the error you got.

How are you calling it? This works:

g = @(x,k) exp(cos(x)).^k;
g(1:5,3)

ans = 1×5
