Hi Jason,
In MATLAB, the xline function is designed to add vertical lines to a plot and allows for customization through various parameters, including adding a label directly to the line. However, this customization needs to be done using 'Name,Value' pairs. When you attempt to pass the string representation of a number directly as an argument, without specifying it as part of a 'Name,Value' pair, MATLAB does not recognize it as a valid input, leading to the "Invalid parameter/value pair arguments" error.
To add a label to your line correctly, you need to use the 'Label' option followed by the string you wish to use as the label. Here's how you can adjust your code:
% Correct way to add Label
xline(ax3,c,'Label',cs);
I hope this clears up the confusion!
