run matlab functions in thread-凯发k8网页登录

run functions in the background

if a function is supported in a thread-based environment, you can use parfeval and backgroundpool to run it in the background.

use the rand function to generate a 100-by-100 matrix of random numbers in the background.

f = parfeval(backgroundpool,@rand,1,100);

for more information about running code in the background, see .

run functions on a thread pool

if a function is supported in a thread-based environment, you can run it on a thread pool if you have parallel computing toolbox™.

parpool("threads");
parfor i = 1:100
    a{i} = rand(100);
end

for more information about thread pools, see threadpool (parallel computing toolbox).

automatically scale up

if you have parallel computing toolbox, your code that uses backgroundpool automatically scales up to use more available cores.

for information about the number of cores that you can use, see the numworkers property of .

by running multiple functions in the background at the same time when you use parallel computing toolbox, you can speed up the following code.

for i = 1:100
    f(i) = parfeval(backgroundpool,@rand,1,100);
end

check thread supported functions

if a matlab function has thread support, you can consult additional thread usage information on its function page. see "thread-based environment" in the extended capabilities section at the end of the function page.

in general, functionality in graphics, app building, external language interfaces, , and environment and settings is not supported.

matlab and several toolboxes include functions with built-in thread support. to view lists of all functions in matlab and these toolboxes that have thread support, use the links in the following table. functions in the lists with warning indicators have limitations or usage notes specific to running the function on threads. you can check the usage notes and limitations in the extended capabilities section of the function reference page. for information about updates to individual thread-supported functions, see the release notes.
