Read certain files from a directory in matlab?
显示 更早的评论
Hello,
I have over 100 .mat files in a directory and I am wondering how can I read and plot some of them. For example the file names are like such:
XX11YZ08 , XX12YZ07, XX13YZ08, XX14YZ06, XX15YZ08, and so on...
I would like to read and plot the data from all the files whose name end with '08'.
Thanks a lot in advance

Hi you can begin your m-file with dir() like
>_>filenames_in_mydirectory=dir()_
then create a cicle (for,while..)
in this cicle use string functions for comparing only last 2 character of the filename (before ".extension" obviously) with the string "08" and save the filenames that match with this condition in an array
after that use load()
mydata=load('myxxxyxylile08.mat'); and so plot data.
good luck

start loop load, plot, hold on maybe clear variable or overwrite if you are running our of memory end loop

files = dir(fullfile('D:\MyFolder\', '*08.mat'))
This gets the file in the form of a structure, how to read the particular file from so that processing can be done on it further.
I have a folder with.tif files and I want to read some specific files so that I can do some processing with those further using geotiffread function.
Thanks.

does anyone know what to change if instead of files = dir(fullfile('D:\MyFolder\', '*08.mat'))
its files = dir ("filesname') but that reads two different file names that are need it and just need from from those two options

Load the file within the 'for' loop and use the plot command followed by 'hold on' (use the hold on and plot within the loop)
if you want each to be in a different color, then you may have to create a string array with the colour codes and use them in the plot command with the (i),,,
Hope this helps
