Open will call your handler function with the following syntax. If you create an M-file function called opencht to handle files with extension. % Keep the dblArray value by assigning it to a variable.Įxample 5 - Using a User-Defined Handler Function % Open a MAT-file containing miscellaneous data.The others are overwritten when ans is reused by MATLAB. This example opens a MAT-file containing MATLAB data and then keeps just one of the variables from that file. open matrixdemos % Opens model matrixdemos.mdl.In this example, open matrixdemos could open either an M-file or a Simulink model of the same name, since both exist on the path.Īs the call, which('matrixdemos'), returns the name of the Simulink model, open opens the matrixdemos model rather than the M-file of that name. It does this by calling which ('filename').

So as said, put your code and excel file in My Documents As to reading the Excel file, use the full path of the file instead of just the file name. When you specify a file without including its file extension, MATLAB determines which file to open for you. This may be the reason matlab can see the files in some circumstances and not others (depends on how it tries to access the files).

If no such file is found, then MATLAB displays an error message.Įxample 3 - Specifying a File Without a File Extension how to run MATLAB in passive (batch) mode, enabling unattended execution on the clusters how to use MATLAB script (.m) files how to plot data, saving the. To open a file that is not on the MATLAB path, enter the complete file specification. If you have a copyfile.m file in a directory that is before toolbox\matlab\general on the MATLAB path, then open opens that file instead.Įxample 2 - Opening a File Not on the Path MATLAB opens the copyfile.m file that resides in toolbox\matlab\general. For example, create a function, openlog, if you want a handler for opening files with file extension. open('filename.xxx') calls the openxxx function it finds on the path. You can create your own openxxx functions to set up handlers for new file types. If no such file name exists, then open displays an error message. If more than one file with the specified filename, name, exists on the MATLAB path, then open opens the file returned by which ('name'). If name does not exist, then open checks to see if name.mdl or name.m are on the path or in the current directory and, if so, opens the file returned by which('name'). Open name.xxx by calling the helper function openxxx, where openxxx is a user-defined function Open the corresponding M-file, name.m, if it exists, in the M-file Editor Open MAT-file and store variables in a structure in the workspace Open array name in the Array Editor (the array must be numeric) The specific action taken upon opening depends on the type of object specified by name. Opens the object specified by the string, name. Open (MATLAB Functions) MATLAB Function Reference
