MATLAB: How to load files in order

if statement

I am looking for How to load files in order

please find attached file

If i = 1:5

data = importdata('RR.data.(i)');

That has error

Use either of the methods shown in the documentation:

For example:

N = 2; % number of files
C = cell(1,N);
for k = 1:N
    F = sprintf('RR.data.%u',k);
    C{k} = dlmread(F);
end
M = vertcat(C{:});

Giving:

>> M
M =
     0   850     0
     0   850     0

Luckily those dates use an ISO 8601 date format, so you can simply import them sorted into character order:

S = dir('*.tif')
F = sort({S.name});
N = numel(F);
C = cell(1,N);
for k = 1:N
    C{k} = imread(F{k});
end

N = 1760;
C = cell(1,N);
for k = 1:N
    F = sprintf('d0.%d.csv',k-1);
    C{k} = csvread(F,2);
end

and after that either vertcat or horzcat:

M = horzcat(C{:})
M = vertcat(C{:})

Alternatively you could preallocate a numeric array of the correct size:

N = 1760;
M = nan(2500,N);
for k = 1:N
    F = sprintf('d0.%d.csv',k-1);
    M(:,k) = csvread(F,2);
end
