how to resolve 'not enough input arguments' error.

I want to convert this code into verilog using HDL Coder.

error is in line 2. ex = exp(x);

code is saved as SOFTMAX_BLOCK.m

function softmax_out = softmax_block(x)
    ex = exp(x);
    softmax_out = ex / sum(ex);
end

code is saved as test_softmax.m

x = SOFTMAX_BLOCK(8)
x = SOFTMAX_BLOCK(5)
x = SOFTMAX_BLOCK(0)

You need to call test_softmax.m which contains the value of x from SOFTMAX_BLOCK.m. Currently value of x is not accessible to SOFTMAX_BLOCK.m. You may refer to these already answered MATLAB Answer which may help you resolve this issue-
