# Validate dry biomass partitioning coefficients

### Description

It attempts to check the requirements of the dry biomass partitioning coefficients.

### Usage

1 | ```
valid_dbp(x, tol = 0.001)
``` |

### Arguments

`x` |
Vector of length equal to 25 containing the dry biomass partitioning
coefficients for the 6 phenological stages as for example produced by |

`tol` |
Numerical tolerance passed to the |

### Value

It will return the vector of coefficients unchanged if no errors are detected.
