How to give heading to matrix in Prime?
Prime (fortunately) works differently than a spreadsheet 😉
This (unfortunately) also means that we do not have much or no options to prettify a matrix when it comes to display a matrix, e.g. by adding nicely formatted row and/or column headers, format single cells, etc.
You may add a first row with the headers as text (probably with "stack"), but it looks a bit ugly because of the quotes and this header can then also interfere with later calculations.
Depending on your need using a table to input data might be an option for a nice display of input data. Here the "headers" actually are the names of the variables (which at the end are all single vectors).
Here is an example how it looks when you add textstrings as headers
I tried the same as image you provided but it is not getting through. I did not use any multiply operator but getting the same error
This should simply work:
What, exactly is the error message you get?
Please attach your worksheet.
Success!
