Hi,
As per my understanding, you created the "Calibrate" switch in the App Designer for Live Data Acquisition and defined a callback for the switch with the conditions mentioned in the code above. Also, it is mentioned that on changing the value of "i" to a whole number the switch is working correctly.
One of the possible workaround for the array could be to initialize the variable "i" before the loop starts, ensuring that the loop is running from the beginning of the "app.indices" array. Please check if "app.indices" is defined and is not empty.
Also, as multiple channels are calibrated you are incrementing "i" in the while loop, therefore it can be replaced by a "for" loop as it will avoid to manually initialize and increment and the loop control statement will handle it automatically.
Please refer to the code snippet below for better understanding:
if app.calibrate == true
for i = 1:numel(app.indices)
data(:,i) = data(:,i) * slope(:,i) + intercepts(:,i);
end
plotGraph(app, data);
elseif app.calibrate == false
plotGraph(app, data);
end
Hope this helps!
