Rubriques

Improve Graphics Performance
Improve the time it takes to update charts and display animations.
What Affects Code Execution Speed
You can improve the execution speed of graphics code by minimizing the effect of two factors that contribute to total execution time.
Judicious Object Creation
Graphics objects are complex structures that store information, listen for certain events to occur, and can cause changes to other objects to accommodate their existence.
Avoid Repeated Searches for Objects
When you search for handles, MATLAB^® must search the object hierarchy to find matching handles, which is time-consuming.
Screen Updates
MATLAB graphics is implemented using multiple threads of execution.
Optimize Code for Getting and Setting Graphics Properties
Certain properties have dependencies on the value of other properties.
Avoid Updating Static Data
If only a small portion of the data defining a graphics scene changes with each update of the screen, you can improve performance by updating only the data that changes.
Use Low-Level Functions for Speed
To maximize graphing performance, use low-level functions and disable certain automatic features.
Transforming Objects Efficiently
Improve performance by taking advantage of the fact that graphics hardware can apply transforms to the data.
System Requirements for Graphics
All systems support most of the common MATLAB graphics features.
Resolving Low-Level Graphics Issues
MATLAB can encounter low-level issues when creating graphics on your system.
