yint

Calculates the integration (differnce quotients) of the vector y = f(x).

---

Usage 1

yint(yvector {, dxscalar=1 {, cscalar=0}})

Result 1

The result is the vector r with nrow(y)+1 elements.

r[0]=c

r[i+1]=r[i]+y[i]*dx; with: i=0..nrow(y)-1

---

Usage 2

yint(yvector, dxvector {, cscalar=0})

Result 2

The result is the vector r with nrow(y)+1 elements. The argument dx contains the differences of the x values and is a vector with nrow(y) elements.

r[0]=c

r[i+1]=r[i]+y[i]*dx[i]; with: i=0..nrow(y)-1

---

Usage 2

yint(yvector, xvector=1 {, cscalar=0})

Result 2

The result is the vector r with nrow(y)+1 elements. The argument x contains the x values and is a vector with nrow(y)+1 elements.

r[0]=c

r[i+1]=r[i]+y[i]*(x[i+1]-x[i]); with: i=0..nrow(y)-1
