Answer 1

[KSSV]

str = 'index_N=10' ;
idx = strfind(str,'=') ;
n = str2num(str(idx+1:end))

There are many other ways too.

Note: If you find the answer useful, accept the answer. you have asked many questions and so far not accepted any answer.

Answer 2

[Andrei Bobrov]

str = 'index_N=10';
out = str2double(regexp(str,'\d*','match'));

Answer 3

HI,

Suppose A = 'index_N=10', then you can get value of index_N by using

eval(A);

it gives index_N = 10 as output.

else you can use

regexp(A, '\d*', 'match')

it writes output 10 in a cell.

Thanks.
