hello all around,

have some problems with matlab with this script (newbie here, should I
precise)


p=[0:0.01:1];
t=(((p/(1.48))+((1-p)*(170E-3))));
v=1/t;



figure(2)
plot(p,v)
xlabel('porosity (%)')
ylabel('velocity (km/s)')


the corresponding error message is :

??? Error using ==> mrdivide
Matrix dimensions must agree.

Error in ==> geovthirdalternative at 33
v=1/t;


I guess that it might a little more complicated to inverse a vector...
Have you any hints to fix this situation ?

pretty thanks !!

Use the element-wise operator with a dot  ./

 v=1./t;
