i have string 1,2,3,4,5,6,5
4,5,6,8,5,8,6
text string 2*7
at the beginning the 2*7 is strings in text file it is not array so put this text into array to deal with a number (str2double)---->to be [ ]
i want to replace only last column 5 and 6 replacing 1 , 2 (specific column 7)
s1=strrep(st,'5','1');
s2=strrep(s1,'6','2');
we have more than one 5 and 6 number i want replacing only the last column (column 7) ?

A=[1,2,3,4,5,6,5;4,5,6,8,5,8,6]
c7=A(:,7)
c7(ismember(c7,5))=1
c7(ismember(c7,6))=2
A(:,7)=c7
