Dear all,

I was wondering what does .uz do in MATLAB?

for example:

plot(Rd.SolutionTimes , intrpUd.uz , 'b' , 'LineWidth' , 2 )

intrpUd is probably a struct with uz being a field.

intrpUd.uz = 2
intrpUd = struct with fields:
    uz: 2
class(intrpUd)
ans = 'struct'

In MATLAB, the .uz syntax is used to access a field or property of a struct object.

In the example you provided, intrpUd is likely a struct object that contains a field or property named uz. The dot (.) operator is used to access this field or property, which is then used as the data for the y-axis in the plot function.

For example, if intrpUd is defined as follows:

intrpUd = struct('uz', [1 2 3 4 5]);

Then intrpUd.uz would evaluate to the vector [1 2 3 4 5]. This vector would be plotted against the x-axis values in the Rd.SolutionTimes vector using the plot function.

So in conclusion, .uz is simply a way of accessing a field or property of a struct object in MATLAB.
