How to subtract one table with another and then plotting the difference

I have 2 tables loaded in my workspace named 'FinalMeasurement' & 'InitialMeasurement'. Both tables are 201x2 and have the same format. How do I subtract the 'InitialMeasurement' table from the 'FinalMeasurement' table and then plot the found difference?

Thanks for any guidance.

The result of this code is a matrix, not a table. You haven't specified X and Y, so I'll assume the first column is X and the second is Y.

D = finalT{:,:}-initT{:,:};
plot(D(:,1),D(:,2))

When it comes to accessing data in a table, I find I keep referring back to this page.

Make sure you data is

• a table (this is a datatype in MATLAB and not a matrix/array)
• You are using your table names and not the ones in my code
