Hi Everyone,
I have many different matrices with one column containing dates and one comlumn containing numerical values.
I need one "Master Matrix" that contains one "Master date" vector and where each numerical value from the other matrices is assigned to the associated date. So in the new matrix each column represents one of the old matrices with only one date vector.
How could I do this?
Thank you very much in advance!
Best, Lisa

i would start collecting all date columns and sort them chronologically and remove double entries (maybe using unique, but i dont know which fornat your date has). the resulting date vector gives you the number of rows of your master matrix. after that you can sort in your numerical vectors column by column and set these rows to NaN to which the data vector does not have a date

Consider storing your time-based data as timetable arrays and use synchronize to synchronize the timetables to a specific date and/or time vector.
