Syntax

results = run(experiment,suite)

Description

results = run(experiment,suite) runs a time experiment on a test suite, and returns an array of TimeResult objects. Each element in results corresponds to an element in suite.

Experiment to collect measurements on, specified as a matlab.perftest.TimeExperiment instance.

Suite of tests, specified as a matlab.unittest.Test array.

Open Script

In your current working folder, create a class-based test, preallocationTest.m, that compares different methods of preallocation.

classdef preallocationTest < matlab.perftest.TestCase
    methods (Test)
        function testOnes(testCase)
            x = ones(1,1e7);
        end

        function testIndexingWithVariable(testCase)
            id = 1:1e7;
            x(id) = 1;
        end

        function testIndexingOnLHS(testCase)
            x(1:1e7) = 1;
        end

        function testForLoop(testCase)
            for i = 1:1e7
                x(i) = 1;
            end
        end
    end
end

Create a test suite.

suite = testsuite('preallocationTest');

Construct a time experiment with a fixed number of sample measurements, and run the tests.

import matlab.perftest.TimeExperiment
numSamples = 10;
experiment = TimeExperiment.withFixedSampleSize(numSamples);
result = run(experiment,suite)

Running preallocationTest
.......... .......... .......... ..........
Done preallocationTest
__________


result = 

  1×4 TimeResult array with properties:

    Name
    Valid
    Samples
    TestActivity

Totals:
   4 Valid, 0 Invalid.
   14.2389 seconds testing time.

Alternatives

If you do not need to create an experiment and test suite explicitly, you can use runperf.
