Owning Class: support
Requires: MathScript RT Module
Syntax
c = argoutnum
Legacy Name: nargout
Description
Returns the number of output arguments you request from the function that calls argoutnum. You can use argoutnum to determine if the number of outputs you request from a function is less than the maximum number of outputs for that function. You then can bypass the calculation of the unrequested outputs. If you attempt to call argoutnum outside of a user-defined function, MathScript always returns 0.
Outputs
| Name | Description |
|---|---|
| c | Returns the number of output arguments you request from the function that calls argoutnum. c is an integer. |
Details
The following table lists the support characteristics of this function.
| Supported in the LabVIEW Run-Time Engine | Yes |
| Supported on RT targets | Yes |
| Suitable for bounded execution times on RT | Not characterized |
Examples
Save the following script as integerdivision.m in the LabVIEW Data directory. The script uses argoutnum to determine if the number of outputs you request from integerdivision is greater than 1. If you request less than two outputs from integerdivision, LabVIEW bypasses the calculation of the remainder output.
function [quotient, remainder] = integerdivision(dividend, divisor)%This is an example for using arginnum and argoutnum.
if arginnum<2
divisor = 1;
end
quotient = floor(dividend / divisor);
if argoutnum>1
remainder = rem(dividend, divisor);
end
After you save integerdivision.m, call the following commands in the LabVIEW MathScript Window or the MathScript Node.
[x, y] = integerdivision(14, 3)[x] = integerdivision(14, 3)
integerdivision(14, 3)
