## Trapezoidal formula for numerical integration

### Description

Numerical integration via trapezoidal formula.

### Usage

    trapzc(step, f)

### Arguments

`step` | step of the grid
`f` | grid evaluation of density

### Value

``int`` | The value of integral computed numerically by trapezoidal formula.

### Examples

    # Example (zero-integral of fcenLR density)
    t = seq(-4.7,4.7, length = 1000)
    t_step = diff(t[1:2])
    mean = 0; sd = 1.5
    f = dnorm(t, mean, sd)
    f.fcenLR = fcenLR(t,t_step,f)
    trapzc(t_step,f.fcenLR)
