Hey guys,
Currently I have 14 .csv files in which I need certain values from ( a column of data ).
the values are all for the same variable and are the maximum temperatures for days in a month ( I have a range from 09/2021 - 10/2022)
What I would like is to collect data from each table into a single nx1 table.
My current for loop works correctly except that it overrides each iteration with the next.
code is as follows:
clear
clc
range = 'D10:D39';
t1 = datetime(2021,09,01);
t2 = datetime(2022,10,01);
t = t1:calmonths(1):t2;
t = convertStringsToChars(string(yyyymmdd(t)));
t = cellfun(@(S) S(1:end-2), t, 'Uniform',0);
for i = 1:length(t);
filename = convertCharsToStrings(append('IDCJDW7021.', t(i), '.csv'));
T = readtable(filename,'Range',range,'ReadVariableNames',false);
end
anythign above the for loop is working fine and besides the data overwrite problem, the for loop is operational.
Will I need to create a table prior to the for loop with the designated size?
Thanks in advance!
Miller

T{i} = readtable(filename,'Range',range,'ReadVariableNames',false);
You can use cell arrays instead
