#LOAD A FILE IN MATLAB CODE#

load( filename, variables ) hundreds the desired variables from the MAT-file, filename.

If filename is an ASCII file, then load(filename) creates a double-precision array containing knowledge from the file. Choose the MAT-file you wish to load and click on Open.Д¬orrespondingly, how do I load an ascii file into Matlab? To load a subset of variables from a MAT-file on the House tab, within the Variable part, click on Import Information. To load saved variables from a MAT-file into your workspace, double-click the MAT-file within the Present Folder browser.

When you partially specify data for a bus that includes a nested bus, you can specify the entire nested bus as and the From File block provides ground values for all elements of the nested bus. To partially specify input data for a bus, you can omit the corresponding field in the structure or specify its value as.

When you load input data for a bus using the From File block, you do not need to provide data for every element in the bus. Then, simulate the model and view the loaded data on the Dashboard Scope block.

#LOAD A FILE IN MATLAB CODE#

To load the bus data, you can run the code to create the busData.mat file using the MATLAB Command Window or select then click the Create bus data to load Callback Button block. The bus, SinusoidBus, contains one signal, Cosine, and a nested bus called SineBus, which contains two signals, Sine and BigSine.Д«usData.Cosine = timeseries(cosdata,time) Д« = timeseries(data,time) Д« = timeseries(ampdata,time) The Bus object in this example defines the bus hierarchy, the names for the signals contained in the bus, and the data type for a nested bus. The PreLoadFcn callback for the model and the code for the Create file with bus data to load Callback Button block both define the SinusoidBus object.ДЄ Bus object defines the bus hierarchy as well as properties of the elements in the bus, such as name and data type. The From File block that loads the bus data has its Output data type setting configured as Bus: SinusoidBus.

The hierarchy and field names in the structure that contains the bus data must match the hierarchy and element names of the Bus object that defines the output data type. When you load bus data using the From File block, you must specify the Output data type parameter as the Simulink.Bus object that defines the bus. Each timeseries object in the structure can contain any kind of data supported when loading data from a single timeseries object. The From File block supports loading a structure that contains timeseries objects as input data for a bus. To load the array data, you can run the code to create the inputData.mat file using the MATLAB Command Window or select then click the Create file with array data to load Callback Button block. The code for the Callback Button block labeled Create file with array data to load creates the time and signal data, concatenates the row vectors into an array, and saves the array to a Version 7 MAT file. The From File block can load array data from any MAT file versions. When you load array data using the From File block, the sample values must be real and double. You can use the From File block to load scalar or vector signal data formatted as an array, where the first row contains time data and subsequent rows contain the sample values. To load the timeseries data, you can run the code to create the inputData.mat file using the MATLAB Command Window or select then click the Create file with timeseries data to load Callback Button block. When you load data using the From File block, the data type for the time values must be double, and the time values must increase monotonically. This example creates and loads ten seconds of data that represents a sine wave.ДЇirst, create a time vector. Data you load using the From File block must contain a time value to correspond to each sample value. The From File block supports loading data stored in timeseries objects and data stored in an array. You can view the code for each Callback Button block in the block dialog or Property Inspector. To create the data, click to select the Callback Button block and click again to run the code. Use the Callback Button blocks to create data in the desired format prior to simulating the model. Create and save timeseries data in the file inputData.mat.Д¬reate and save input data for the bus in the file busData.mat.Д¬reate the Simulink.Bus object that defines the output data type for the From File block that loads data for a bus.
