MATLAB Programming Fundamentals - MathWorks

Valid: 1

Samples: [4×7 table]

TestActivity: [8×12 table]

Totals:

1 Valid, 0 Invalid.

As indicated by the size of the TestActivity property, the performance testing

framework collected 14 measurements. This number includes 4 measurements to warm

up the code. The Samples property excludes warm-up measurements.

Display the sample measurements for the first test.

Compute Statistics for Single Test Element

Display the mean measured time for the first test. To exclude data collected in the warm-

up runs, use the values in the Samples field.

sampleTimes = results(1).Samples.MeasuredTime;

meanTest = mean(sampleTimes)

meanTest =

0.0900

Compute Statistics for All Test Elements

Determine the average time for all the test elements. The fprintfTest test includes two

different methods. Compare the time for each method (test element).

Since the performance testing framework returns a Samples table for each test element,

concatenate all these tables into one table. Then group the rows by test element Name,

and compute the mean MeasuredTime for each group.
