I would like to write the constraints between two continuous decision variable x(m) and y(n)

x(m) is equal to the value of column in y(i,j) which is nonzero

i.e.   y=[1,1,0,0,1] and x could be one of [1,2,5]

I wonder if this relation could be written in linearization type or

if there some ways to transform this constraints into gurobi language ?

( I use matlab In fact, there is a function in matlab called "find"

but I could not figure out how to use it since matrix A  is still can not be written)

 

thanks a lot !

  Hi Ray,

  I am not completely sure, what you are looking for but maybe writing an LP file can help. You can use the grb_write function to do this.

  Cheers,
  Matthias
