Hello Hari,

While using dir command, the default sorting order is lexicographical order which results in the order 1, 10, 100, ... . To sort it according to the numeric values, you need to extract the file names and do it manally. You can use str2double function for this purpose. Please find the documentation to the same: https://www.mathworks.com/help/matlab/ref/str2double.html.

Using this function you can convert the file names to numeric values and then apply sorting on those values.

I hope this helps!
