dget_l_V1: Growth for v1 morph between maturity thresholds
In Echinophoria/DEB_output: Dynamic Energy Budget exploration tools

Description Usage Arguments Value Author(s) References Examples

Calculates the growth assuming a v1 morph. Exponential growth during the accelerated stage in the case of abj models. This function can be used for the calculation of the length at metamorphosis.

1	dget_l_V1(vH, l, parms)

`vH`	a vector with the maturity levels at different stages thresholds to calculate growth between them.
`l`	initial scaled length at the starting maturity level.
`parms`	a vector containing the parameters: k: -, maintenance ratio; g: -, energy investment ratio; f: -, scaled functional response; lref: -, reference scaled length, also the length at the begining of the exponential growth, in many cases equal to l.

l, scaled length during the maturity interval evaluated. The last value will be the length at the ending maturity threshold.
