**Syntax**

**Description**

```
[breaks,coefs,l,k,d] = unmkpp(pp)
```

extracts, from the piecewise polynomial `pp`

, its breaks `breaks`

, coefficients `coefs`

, number of pieces `l`

, order `k`

, and dimension `d`

of its target. Create `pp`

using `spline`

or the spline utility `mkpp`

.

**Examples**

This example creates a description of the quadratic polynomial

as a piecewise polynomial `pp`

, then extracts the details of that description.

pp = mkpp([-8 -4],[-1/4 1 0]); [breaks,coefs,l,k,d] = unmkpp(pp) breaks = -8 -4 coefs = -0.2500 1.0000 0 l = 1 k = 3 d = 1
