assign variable name to Function Output Variables

Hi All

when using a Function it is possible to assign a variable name to the input

e.g

wave = Uph

[.........] = waveform(wave)

Is it possible to use the same variable in the output definition

[wave_rms]=waveform(wave)

so the output variable stored in the workspace is Uph_rms and not wave_rms?

Thanks

Adrian

Why don't you just change [wave_rms]=waveform(wave) into [Uph_rms]=waveform(wave) ?

[Guillaume]

And note that the brackets are not necessary

wave_rms = waveform(wave); 
uph_rms = waveform(uph);

The variable to which you assign the output of a function to call does not have to match the name that is defined in the function signature. This is exactly how it works for built-in functions, it's no different for the function you write.

Adrian's comment originally posted as an answer moved here:

I have 20 waveforms to process and i dont want to hard code each function

e.g

wave=Uph

[wave_rms]=waveform(wave)

then

wave = Vph

[wave_rms]=waveform(wave)

my function has 15 output definitions so would take a long time to hard code.

These 20 waveforms are they 20 different variables? or are they more sensibly stored in a container of some sort (cell array, matrix, table,...)?

They are 20 different variables

They are 20 different variables

That's where you went wrong and what we have to fix. How were these 20 different variables created in the first place.
