Flowmatrix

Given a linear inverse model food web input list, generates a flow
 matrix, that contains the values of flows

utilities

Functions that read and solve linear inverse problems (food web problems, linear programming problems).
These problems find solutions to linear or quadratic functions:
min or max (f(x)), where f(x) = ||Ax-b||^2 or f(x) = sum(ai*xi)
subject to equality constraints Ex=f and inequality constraints Gx>=h.

Flowmatrix function

<dl> <dt>lim </dt>
<dd>a list that contains the linear inverse model
 specification, as generated by function <code>setup.limfile</code>.</dd> <dt>web </dt>
<dd>the solved (food) web problem, i.e. the values of the
 unknowns; if not specified, the model is solved first, using <code>Lsei</code></dd></dl>
