文字列ベクトル. モジュール名またはツールボックスの絶対パスを指定します.
a vector of string. Contains the paths to directories of modules to test. If "/path/to/directory"
is given as input parameter, tests are retrieved in the subdirectory
/path/to/directory/tests/benchmarks
.Used for homemade benchmarks.
a vector of string. Contains the names of the tests to perform.
The name of a test is its filename without .tst
. If several modules or directory are given as first input parameter, scans for tests in each of these modules or directory.
![]() | Partial test names are allowed to run a subset
of benchmarks dedicated to the same function/feature.
For instance, specifying "ascii"
will select all tests (in given module(s)) whose names
contain "ascii" (See examples). |

"nb_run=value"
: runs each benchmark value
times ; by default bench_run
runs 10000 times the code between BENCH START and BENCH END tags (see below). Overrides any BENCH NB RUN
specified in the benchmark test files.
a single string
File path to the result of the bench_run
in xml format. By default, or if "", "[]"
or []
is given, the output directory is TMPDIR/benchmarks/
.
If exportToFile
is a directory, creates a timestamped output file is the directory, otherwise creates the file exportToFile
. If the file could not be created a warning is issued and the file is created under TMPDIR/benchmarks/
instead.
a N-by-2 matrix of strings
the first column lists the modules tested by bench_run
, the second column lists the names of the benchmarks
a vector of doubles
the execution time for each benchmark
a vector of doubles of size N
the number of iterations of respective test
Performs benchmark tests, measures execution time and produces a report about benchmark tests.
Searches for .tst files in benchmark test library or input parameter path under tests/benchmark
subdirectory,
executes them 10000 times and displays a report about execution time.
Special tags may be inserted in the .tst file, which help to control the processing of the corresponding test. These tags are expected to be found in Scilab comments.
These are the available tags :
<-- BENCH NB RUN : 10 -->
By default, this test will be repeated 10 times, unless the "nb_run=###"bench_run(..)
option is used. The value given for the flag can be set to any integer value.
// <-- BENCH START --> [code to be executed] // <-- BENCH END -->
Code between these tags will be repeated. Any code written before/after will be executed only once before/after the repetition, without being timed. If these tags are missing, the entire code will be repeated.
