Code Execution

Evaluate expressions or functions indirectly, set timers

MATLAB^®  includes functionality to indirectly evaluate expressions and to set timers for program execution.

Functions

`eval`	Evaluate MATLAB expression
`evalc`	Evaluate MATLAB expression and capture results
`evalin`	Evaluate MATLAB expression in specified workspace
`feval`	Evaluate function
`run`	Run MATLAB script
`builtin`	Execute built-in function from overloaded method

`timer`	Schedule execution of MATLAB commands
`delete`	Delete files or objects
`get`	Query graphics object properties
`isvalid`	Determine valid handles
`set`	Set graphics object properties
`start`	Start timer
`startat`	Schedule timer to fire at specified time
`stop`	Stop timer
`timerfind`	Find timer objects
`timerfindall`	Find all timer objects
`wait`	Block command prompt until timer stops running

`parfevalOnAll`	Run function on all workers in background
`parallel.pool.Constant`	Copy or create data only once on workers in parallel pool (Since R2021b)
`canUseGPU`	Verify supported GPU is available for computation
`canUseParallelPool`	Verify that parallel functions can use a parallel pool (Since R2020b)

Schedule Command Execution Using Timer

To schedule the execution of MATLAB commands, create a timer object.
- Timer Callback Functions
- Handling Timer Queuing Conflicts
Create Hyperlinks that Run Functions
Functions that support the matlab: keyword can display hyperlinks, which execute commands when you click the hyperlink text.
Alternatives to the eval Function
Although the eval function is very powerful and flexible, it is not always the best solution to a programming problem. In many instances, there are recommended alternative approaches to using eval.
Run Parallel Language in MATLAB
You can run parallel code in serial if you do not have Parallel Computing Toolbox™.
