Signal Logging

Data logging to workspace or file, external mode scope triggering

To debug a small section of a lengthy simulation, trigger data capture in external mode by using a trigger signal. Log the data to your workspace and to a MATLAB^® file for later analysis.

Topics

Log to Workspace

Signal Logging to the Workspace

Save data to a variable in the MATLAB base workspace.

STEP 1: Set Scope Parameters for Logging to Workspace
STEP 2: Set External Mode Properties for Logging to Workspace
STEP 3: Plot Signal Data Logged to Workspace

Log to File

Signal Logging to a File

Save data to a file on the development computer.

STEP 1: Set Scope Parameters for Logging to File
STEP 2: Set External Mode Properties for Logging to File
STEP 3: Set External Mode Data Archiving Parameters
STEP 4: Plot Signal Data Logged to File

File System I/O

Learn about the file system capabilities and constraints of Simulink^® Desktop Real-Time™.

Featured Examples

Execution Time Measurement and Block Profiling

Analyze model execution performance in Simulink Desktop Real-Time™. The example is a multirate multi-tasking model that performs a time-intensive operation of matrix multiplication and finding the minimum in the resulting matrix product. This is being done for two different matrix sizes at two different sample rates.
