Print data to txt file matlab

In this example, we will use the fprintf function to write data to a test file. The data to be written will be an array of integers. As we can see in the output, the fprintf function has written our data to the file created. We will try to edit the same file created in the above example. As we can see in the output, the fprintf function is not able to write the new data to our file. This is because we only had read-only permission for this file and were not able to edit it.

Maybe there are some things wrong in the syntax. Matlab can not run the code you provided. Phan - which example of code did you run, and what was the error? For the first example, the if block should look like. I just ran both examples now, and the code worked fine for each given your inputs. Oh, I did it! Thank you so so much!!! Glad that it worked!

Create a table T2 which includes row names using the RowNames name-value pair argument. Export T2 to a tab-delimited text file named tabledata2.

Use the Delimiter name-value pair argument to specify a tab delimiter, and the WriteRowNames name-value pair argument to include row names. Use fprintf to export the cell array by specifying the format of the output data. Alternatively, import the cell array using fprintf. Open a file that you can write to named celldata.
