What is the args for codegen for a double?

This is my function ... function funcX(voltage_0,voltage_1,current,voltge_setting)

How do I create the codegen command-line ? Those are function inputs are all double data types.

Hi Garrett,

To compile a function that takes arguments simply use "codegen fcnName -args" followed by a cell array of example input values.

So, assuming that you want to compile funcX and "voltage_0","voltage_1","current", and "voltge_setting" are all meant to be scalar doubles you could run the following from command line:

 codegen funcX -args {1,2,3,4}

More information on the codegen command is provided at: https://www.mathworks.com/help/coder/ref/codegen.html

I have a question, let's consider that instead of entering the scalar variables, I want to enter as an array, what would be the syntax?

for example: function ... function funcX(V) , where V = [voltage_0,voltage_1,current,voltge_setting]

If you want the array to be the same size as V and have V assigned in your workspace, just do:

codegen funcX -args V

You can use coder.typeof to make the argument variable-sized

codegen funcX -args coder.typeof(V, [100, Inf], [1, 1])

To pass a :100 x :? variable-sized array.

Dear Ryan,

Thank you. I have another question, if I have several entries (scalars and arrays), can you tell me what the syntax with variable length of arrays would be like ?. Another thing, can the "varargin" variable be used as well?
