How to extract number from this string cell?

Hi everyone,

I have a string array like below:

") injection-dr0015:138751)"

") injection-dr0015:68761)"

") injection-dr0015:122762)"

") injection-dr0015:83759)"

") injection-dr0015:163753)"

I would like to extract the numbers after : , like:

138751

68761

122762

83759

163753

I appreciate for any ideas or solution.

Thank you.

Try something like this —

C = [") injection-dr0015:138751)"
     ") injection-dr0015:68761)"
     ") injection-dr0015:122762)"
     ") injection-dr0015:83759)"
     ") injection-dr0015:163753)"];
E = str2double(extractBetween(C, ":",")"))

E = 5×1

138751 68761 122762 83759 163753

.

Try this (one of several ways):

str = [") injection-dr0015:138751)"
") injection-dr0015:68761)"
") injection-dr0015:122762)"
") injection-dr0015:83759)"
") injection-dr0015:163753)"];
strNumbers = cell(numel(str), 1);   % Use this if you want as character arrays
dblNumbers = zeros(numel(str), 1);  % Use this if you want double numbers
for k = 1 : numel(str)
    thisString = char(str(k));
    index = strfind(thisString, ':') + 1;
    % Use this if you want as character arrays:
    strNumbers{k} = thisString(index : end-1);
    % Use this if you want double numbers.
    dblNumbers(k) = str2double(strNumbers{k});
end
strNumbers

strNumbers = 5×1 cell array
    {'138751'}
    {'68761' }
    {'122762'}
    {'83759' }
    {'163753'}

dblNumbers

dblNumbers = 5×1

138751 68761 122762 83759 163753
