In matpower you can write code or directly you can use makePTDF fucntion but it will give ISF matrix.From that you have to calculate PTDFs using below formula PTDF(l,m)=ISF(l,0)-ISF(m,0) 0-slack bus

For ISF you may write
mpc=loadcase('case9');
ISF=makePTDF(mpc);
To calculate PTDF between x and y
PTDFxy=ISF(:,x)-ISF(:,y);
