MATLAB: Read set framents of string.

file nameMATLABstring

I have a lot of strings and I want only to read part of them and write to variable value of the string example :

abcdefghR12X478Y124

I need to read a coordinates of this file

so X – 478

and Y – 124

what is the best way to extract it from the file name and write to X variable and Y variable.

>> s = 'abcdefghR12X478Y124';
>> X = str2double(regexp(s,'(?<=X)\d+','match'))
X =
   478
>> Y = str2double(regexp(s,'(?<=Y)\d+','match'))
Y =
   124

MATLAB: Extract numbers from mixed string.

There are probably better ways to do this but if this is always going to be the string and only the numbers are going to change, you can use strfind() to get the locations of "temp"

Something like this:

xStr = strfind(Str, 'temp');
temp_1 = str2double(Str(xStr(1)+4:xStr(1)+6));

You should then be able to figure out temp_2....

>> S = 'Delft_2_220_20_4344-5088.csv';
>> V = str2double(regexp(S,'\d+','match'))
V =
           2         220          20        4344        5088

Using indexing to allocate those values to whatever other variables you want.
