¿Cómo se cargan datos desde el espacio de trabajo?

How do you load data from workspace?

To load saved variables from a MAT-file into your workspace, double-click the MAT-file in the Current Folder browser. To load a subset of variables from a MAT-file on the Home tab, in the Variable section, click Import Data. Select the MAT-file you want to load and click Open.

Variables specific to a function workspace are called local variables. That is, you cannot call a function or script that assigns values to variables unless those variables already exist in the function workspace.

When you load data for a bus, specify the Output data type parameter as the Simulink. Bus object that defines the bus. Real signals of type double can be in any data format that the From Workspace block supports. For complex signals and real signals of a data type other than double , use any format except Array .

Select Workspace To view the current workspace, select the Editor tab. The Function Call Stack field shows the current workspace. Alternatively, you can use the dbstack function in the Command Window.

To import data from a file, do one of the following:

1. On the Home tab, in the Variable section, select Import Data .
2. Double-click a file name in the Current Folder browser.
3. Call uiimport .

To load data using the From Workspace block, you must create or save the data using a format the From Workspace block supports in the base, model, or mask workspace. You could programmatically create the data you load, load data logged in another simulation, or load real-world data collected from sensors or in a lab.

Create Data Objects from Built-In Data Class Package Simulink

1. In the Model Explorer Model Hierarchy pane, select a workspace to contain the data objects. For example, click Base Workspace .
2. On the toolbar, click the arrow next to Add Parameter or Add Signal .
3. To create more objects, click Add Parameter or Add Signal.

The workspace contains variables that you create or import into MATLAB from data files or other programs. You can view and edit the contents of the workspace in the Workspace browser or in the Command Window. For more information, see Create and Edit Variables.

Undefined function or variable ‘data’. Where is the error? The variable data was probably defined outside of the function, so it is out of scope. Pass data as a parameter to compute and then it will be available inside the function. You can use evalin to work with variables from another workspace. In your example this could be

In most cases, variables created within a function are local variables known only within that function. Local variables are not available at the command line or to any other function. However, there are several ways to share data between functions or workspaces.

If you need to use the data inside a function, then run that COM server code inside the function so you get the data right inside the function workspace. If you also need to use the data somewhere else, or multiple functions, then make a function to read all the .xls file and put the result data in the return argument.

Call the update1 function from the command line and assign to variable Y in the base workspace: A nested function has access to the workspaces of all functions in which it is nested. So, for example, a nested function can use a variable (in this case, x) that is defined in its parent function:
