using QuantLib interpolator

Posted by Pavan Shah-2 on

how can i convert a string from my map to a Real that I can then use as a value in a vector <Real> to be passed into QuantLib's interpolator constructor.

for example

i have

string testvol = Input_Vols["GBPUSDV9M CMPN Curncy"].at(1);

 vector <Real> xvec (10), yvec(10);

xvec[0]=1; yvec[0]= atof(testvol);

this doesn't work.  should i be using something other than atof()?

It says "no suitable conversion function from string to const char *."

Input_Vols above is a map <srting <vector <string> > .

any ideas ?

thanks

Pavan
