Data acquisition (Analog Input)

Anyone got idea what wrong with this coding?

%%Step 1: Create an analog input object to communicate with data acquisition device
% In this case, a Windows sound card is used ('winsound').
ai = analoginput('winsound');
addchannel(ai,1);

Here is the error :

??? Undefined function or method 'analoginput' for input arguments of type 'char'.

Error in ==> sound_acquisition at 15
ai = analoginput('winsound');

Is that my matlab missing of data acquisition toolbox?

Thanks in advance!

First you need to ensure that you have licensed the toolbox, which might require additional purchase. If you did need to do an additional purchase then afterwards in the command window Help section there is menu item to update the license.

Once it is licensed then in the command window, Add-ons, Get Add-ons, search for the toolbox and pull up the information for it. Then near upper-right there will be a button to install the toolbox (if it is not licensed yet then the button would be to purchase it instead). Click, agree to the license, and it will install.
