MATLAB: Get error “Undefined function or variable ‘xml_write’.”

MATLAB

I am trying a simple code to test xml_write but I got this:

Undefined function or variable 'xml_write'.

Why?

Best Answer

Just found out why, I didn't use import. Now it works.

MATLAB: Writetable() Error: Undefined function ‘write’ for input arguments of type ‘double’

writetable writes the table to a file, but not matrices of type double. So try to convert the matrix to a table at first.

Please post the code for writing the Excel file.

Notice the limitations of xlswrite:

 If your computer does not have Excel for Windows&reg;, or if the COM server 
(part of the typical installation of Excel) is unavailable, then the xlswrite
function:
* Writes array A to a text file in comma-separated value (CSV) format. A must be a numeric matrix.
* Ignores the sheet and xlRange arguments.

A general hint: The documentation of Matlab is very useful. If you have problems with a specific command, reading the corresponding docs is a better help than in any other software I've used.

MATLAB: Can’t I concatenate input variable to file extentsion in another variable

Since you do not return the variable named faif from the function, once the function call ends it is destroyed along with the rest of the function's workspace.

Do you want to write Tone_with_silence to the file with that name? If so, it's easiest to do that inside the function.

Do you want to use the filename stored in faif (and possibly the Tone_with_silence) variable outside this function? If so, declare the function to return them as output arguments and call the function with output arguments.

See this documentation page for basic information about function workspaces.

Note that both declaring the function's output arguments in its definition and calling it with output arguments are necessary. MATLAB doesn't "magically" put the output arguments you declare the function to return in its caller's workspace. I mention this only because I've seen people in the past assume that behavior.
