How does one append a Nx1 logical to the right of a Nx4 table?
I assumed this would be a matter of horzcat(initialTable, logicalColumn)
But, I recieve an error of "All input arguments must be tables."
So the real question is:
how to convert the Nx1 logical column to a "table", such that I can horzcat the tables?
Thank you

Use the addvars function —
T1 = array2table(rand(10,4), 'VariableNames',{'A','B','C','D'})
T1 = 10×4 table

LogicalVector = rand(10,1)>0.5;
T1 = addvars(T1,LogicalVector,'After','D')
T1 = 10×5 table
