i know this question is here very often, but i cant solve this and i would appreciate your help. I have .txt file and i am looking for specific string - e.g. value and then copy a number behind that to a matlab memory.

example

1. row1


2. row2


3. pressure 95.8 %there could be more white-space characters between string and numbers and in every cycle there is different value:1.cycle 95.8>>next cycle 1009.6543>>..., but its always in this format

I tried this

fid = fileread('search.txt')

value = regexpi(fid, '(?<=pressure\s*)\d*', 'match')

but it saved just '95' instead of '95.8' thanks, for any help
