# intc

integral de Cauchy

### Seqüência de Chamamento

```[y, err] = intc(a, b, f)
[y, err] = intc(a, b, f, abserr)
[y, err] = intc(a, b, f, abserr, relerr)```

### Parâmetros

a,b

dois números complexos

f

função externa

abserr, relerr
real scalars: absolute and relative errors. Default values: `1.d-13` and `1d-8`.

err
real number: estimated absolute error on the result.

### Descrição

Se `f` é uma função com valores complexos,`intc(a,b,f)` computa o valor da integral de `a` a `b` de `f(z)dz` ao longo da reta `a b` do plano complexo.

### Exemplos

```function y=f(z)
y = z^(3 + %pi * %i);
endfunction

intc(1+%i, 4-%i, f)

[r, err] = intc(1+%i, 4-%i, f, 1d-10, 1d-6)```

### Ver Também

• intg — integral definida
• intl — integral de Cauchy

### Histórico

 Version Description 5.5.0 Absolute and relative (input) and absolute (output) errors management added. 6.1.0 The default abserr value becomes 10-13 instead of 10-14.
