Add A Variable To A Mat File

The third and fourth variables topomap1 and topomap2 are both arrays containing topography data load the elevation data from the third column of each variable into a field of the structure array s for each field specify a field name that is the original variable name prefixed by elevationof.

Add a variable to a mat file.

For example you can save data to a subset of a variable in a mat file or read a subset of a variable into the matlab workspace. Atomic combat saved game files is another file format that has a similar file extension of mato but those types of files open with atomic combat. Save filename variables append adds new variables to an existing file. For ascii files append adds data to the end of the file.

I have a data in the following format. To append to a version 6 mat file you must also include v6 as an input argument. Files with the mat extension are files that are in the binary data container format that the matlab program uses. To add one o more variables to an existing mat file you can use the save function by specifying the option append.

Select the mat file you want to load and click open. Load the mat file into a struct using the load function. Save data to a subset of a variable y in the file myfile2 mat using the mat file object. To load a subset of variables from a mat file on the home tab in the variable section click import data.

If a variable already exists in a mat file then save overwrites it with the value in the workspace. To load saved variables from a mat file into your workspace double click the mat file in the current folder browser. Each read variable will be stored in a field of the struct. I j k val where i j k are variables and val is the corresponding data at i j k values.

Remove from that struct the the field corresponding to the varaible you want to delete. Varlist is a cell array containing the names of the four variables in topography mat. The extension was developed by mathworks and mat files are categorized as data files that include variables functions arrays and other information. You also can drag the desired variables from the current folder.

To remove one or more variables from an existing mat file you can.
