Delete Columns from a table where the 1st element in the column is a negative number?

2 visualizzazioni (ultimi 30 giorni)
I have a number of tables that contain sensor data from 8 channels and the 1st row in the table is the time this data was sampled at.
I want to delete all the data from the columns where the 1st element in the column is a negative number
How do I do this?

Your screenshot does not appear to be that of a matlab table. It looks like you have a matrix, so:
yourmatrix(:, yourmatrix(1, :) < 0) = []; %delete all rows of the columns whose 1st row is negative.
Your data would probably be better stored in a matlab table or even better a timetable. For that you'd have to transpose your matrix so that the time is in column format.

I am very new to Matlab, still trying to get my head around tables and matricies
