ToMatFile
This block exports Activate data as a MAT file.
Library
SignalExporters
Description
The ToMatFile block exports Activate data to a MAT file. At simulation instant chosen in Advanced tab, the time and the variable values are saved in the MAT file.
The lengths of the time element and variable element are identical.
The created MAT file can be read by the FromMatFile block or any tool capable of reading a MAT file.
The FromMatFile block can regenerate the original signal fed to the ToMatFile block.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
fname | Matfile name | Name of the MAT file. | String | |
tvarname | Time variable name | Name of the variable in the data structure that contains the time values. If no name is provided, the time variable is not exported. In this case, the external activation should be enabled to store data at event instants. | String | |
nin | Number of inputs | Number of data channels to be writte in the MAT file. | Number | |
inports | Output port parameters | Structure | ||
inports/varnam | Variable name | Cell of strings | ||
externalActivation | External activation | Specifies whether the block receives an external activation or inherits its activation through its regular input ports. When External Activation is selected, an additional activation port is added to the block. By default, external activation is not selected. | Scalar | 0 |
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
subsample | Sub-sampling rate | Sub sampling rate should be greater than 1. | Scalar | |
increasingTime | Strictly-increasing time | Select for the block to create a strictly-increasing time sequence. | Number | 0 |
matfileversion | Matfile version | Version of the MAT file. Available options are 5 (default) and 7.3. | String | '5' |
Compressed | Generate a compressed Matfile | Default is ON. | Scalar | 0 |
R_MP | Register mesh points | Register the continuous time step. Event code is 0. | Number | 0 |
R_DE | Register discrete events | Register the discrete time event. Event code is 1. | Number | 0 |
R_MPLL | Register left limit of discrete events | Register the event just before a discrete event. Event code is -1. | Number | 0 |
R_ZCLL | Register left limit of zero crossings | Register the event just before a zero crossing event. Event code is 4. | Number | 0 |
R_TRY | Register try points | Register the events in try phase. Event code is 2 or 3. | Number | 0 |
Ports
