As the offline variant of Matrix2Wolfram-Online this tool can be used to offline convert matrices that are separated by spaces and newlines into the format that Wolfram|Alpha uses for its matrices.
The tool can also be used without a UI to convert the matrix in your clipboard. For this, just add the -nogui flag!
This project, as well as every other VisualBasic Classic project, is not completely supported on modern systems anymore.
Some of these tools now suddenly need administrator rights to execute, which they didn’t when I programmed them. I, as a random guy from the internet, would not suggest you to execute them with these.
