Help Center Help Center. Create variable matVar1 with a 2-by-3 matrix of uniformly distributed random numbers between 0 and 1.

Help Center Help Center. You can either save the figure to a FIG-file or you can generate and save the code. Create a plot to save. Add a title and axis labels. Save the figure to a FIG-file using the savefig function. The FIG-file stores the information required to recreate the figure. Close the figure, then reopen the saved figure using the openfig function.

Matlab save

Help Center Help Center. You can save and load parts of variables directly in MAT-files without loading them into memory using the matfile function. The primary advantage of using the matfile function over the load or save functions is that you can process parts of very large data sets that are otherwise too large to fit in memory. When working with these large variables, read and write as much data into memory as possible at a time. Otherwise, repeated file access can negatively impact the performance of your code. This example shows how to load, modify, and save part of a variable in an existing MAT-file using the matfile function. Create a Version 7. By default, matfile only permits loading from existing MAT-files. To enable saving, call matfile with the Writable parameter. Alternatively, construct the object and set Properties. Writable in separate steps. Load the first row of B from example. When you index into objects associated with Version 7. Update the values in the first row of variable B in example.

Based on your location, we recommend that you select:. Off-Canvas Navigation Menu Toggle. In Rb, the saveas function matlab save a warning when you export a figure to one of these file formats.

You can use save in the functional form as well as the command form shown above. When using the functional form, you must specify the filename and instrument objects as character vectors. Any data that is associated with the instrument object is not automatically stored in the MAT-file. For example, suppose there is data in the input buffer for obj.

Help Center Help Center. However, you can save any or all the variables in the current workspace to a MAT-file. To save a subset of your workspace variables to a MAT-file, select the variables in the Workspace browser, right-click, and then select Save As. You also can drag the selected variables from the Workspace browser to the Current Folder browser. Variables that cannot be saved to a script are saved to a MAT-file with the same name as that of the script. You also can save workspace variables programmatically using the save function.

If filename does not include a full path, the save function saves to the current folder. Your variables are: matVar1 matVar2 matVar3. To control the size or resolution when you save a figure, use the print function instead. Instead, call the size method for MatFile objects. This type of format scales well, but can result in a large file. In a future release, the saveas function will no longer support saving UI components in figures. Create several variables and use command syntax to save them to a file called myMat. Main Content. For very large files, the best practice is to read and write as much data into memory as possible at a time. To view or set the default version for MAT-files, go to the Home tab and in the Environment section, select Preferences. Create a bar chart and save it as an EPS file. If you specify other types of graphics objects, such as an axes, then saveas saves the parent figure to the object.

Syntax saveas h,'filename. The format of the file is determined by the extension, ext. Allowable values for ext are listed in this table.

If you do not specify filename , the save function saves to a file named matlab. Call the exportgraphics function. Restore Listeners You can restore property listeners from the loadobj method.
