how to perform string to double in matlab using delimiter

Question

I have 1x14 char output

A = '   3691/1784  '

What I want to get is

P = 3691

Q = 1784

I have tried the following as explained in another answer here:Specify decimal separator for .dat file in matlab

output=str2double(strrep(P,'/','.'))

But the output is 3612.1784.

Any help will be highly appreciated.

You mean `output=str2double(strrep(A,'/','.'))`, right? – A. Donda Mar 16 '15 at 15:19 — A. Donda, Mar 16 '15 at 15:19

Try this:

output = str2double(regexp(A, '\d+', 'match'));

Or, if the numbers may contain a decimal part,

output = str2double(regexp(A, '\d+(\.\d*)?', 'match'));

Didn't know `str2double` converts a cell array of strings to an array of doubles. – A. Donda Mar 16 '15 at 15:22
@A.Donda Yes, it's very handy for that – Luis Mendo Mar 16 '15 at 15:24

Using strsplit and deal:

output = deal(str2double(strsplit(A,'/')))

Might be overkill for this case but that's an alternative haha
