Hi,
I have cell array as shown below:
A050K190E3T15R40
B060L110E8T15R43
F050K230E2T25R40
G050K590E2T15R40
P050L590E2T15R40
I want to take the numerical part left side to the "E" and immediate right side numerical part of "E" and Including "E".
Desired Output:
190E3
110E8
230E2
590E2
590E2

Regular expressions for the win.
out = regexp(in,'\d*E\d*','match','once');
The 'once' means one time per cell element, and greatly simplifies the output if you know for sure there should only be one match in each element.

The example looks like you want the substring from the indices 6 to 10:
Data = {'A050K190E3T15R40', ...
'B060L110E8T15R43', ...
'F050K230E2T25R40', ...
'G050K590E2T15R40', ...
'P050L590E2T15R40'};
Result = cellfun(@(c) c(6:10), Data, 'UniformOutput', 0)

No Sir,
It's not fixed to extract 6~10 indices. I just need to trace "E", and extract numerical left & right side to "E" including E.
A050K190E3T15R40
B060L110E8T15R43
F050K230E2T25R40
G050K590E2T15R40
P50L590E2T15R40
K70L59E2T15R40
As40L5E2T15R40
Desired Output:
190E3
110E8
230E2
590E2
590E2
59E2
5E2
