You can't directly convert them. RRF files are just a packet log that the client will read back as a replay. You have to use a screen recording software to record the replay client into to make it a video.

Reduced row-echelon form (rref) can be obtained on the TI-89 in one step by using rref(matrix). To enter rref(, press CATALOG button (Row 3 Column 3), followed by s (key 3) and then use the up arrow to select rref(. Press ENTER button to place rref( on the command line.

You cannot use mfilename in the command window . You cannot pause execution in the command window . In r2016b and later you can define scripts in script files . With newer matlab releases you can use the editor interface to pause a script .

Launch MATLAB and click “File” in the menu bar at the top of the window. Click “Set Path” and search the pop-up file browser for the folder to set as your MATLAB path variable. Alternatively, leave the path set to the default folder. In Windows Explorer, drag and drop a CSV file in any folder on the MATLAB path.

In general, if A is in RREF, then a basis for the nullspace of A can be built up by doing the following: For each free variable, set it to 1 and the rest of the free variables to zero and solve for the pivot variables. The resulting solution will give a vector to be included in the basis.

To import data from a CSV file into MATLAB use the “readtable” function. The “readtable” function automatically detects the header and the number of lines to skip.
