b=regexpre​p(b,'^','.​^','all'); doesn't works.

I want to replace ,/,^ to .,./,.^

my code:

syms t;

a='t^3+t*t+t^2/t';

b=a;

b=regexprep(b,'*','.*','all');

b=regexprep(b,'/','./','all');

b=regexprep(b,'^','.^','all');

Result I want:

a=t^3+t*t+t^2/t

b=t.^3+t.*t+t.^2./t

Real result:

a=t^3+t*t+t^2/t

b=t^3+t.*t+t^2./t

I think " b=regexprep(b,'^','.^','all');" doesn't works.

How can I fix this problem?

syms t;
a=t^3+t*t+t^2/t;
b = vectorize(a);

b=regexprep(b,'\^','.\^')

STRREP is faster than REGEXPREP:

b = strrep(b, '^', '.^');
