I have thousands of string variables from where I want to delete some character (both from start and end). For example I want to convert
'TENSOR 27_SN2837_CSN_PROV1_20130209.0.csv' to CSN_PROV1_20130209
'TENSOR 27_SN2837_CSN_WADC1_20131004.0.csv' to CSN_WADC1_20131004
............
...........
Any suggestions?. Thanks

There may be more efficient ways to do this, but if all the original strings are the same length, this works:
V = ['TENSOR 27_SN2837_CSN_PROV1_20130209.0.csv'
'TENSOR 27_SN2837_CSN_WADC1_20131004.0.csv'];
for k1 = 1:size(V,1)
I1 = strfind(V(k1,:), 'CSN');
I2 = strfind(V(k1,:), '.0');
W(k1,:) = V(k1,I1:I2-1);
end
producing:
W =
CSN_PROV1_20130209
CSN_WADC1_20131004
