[Scilab-users] column vector consisting of the respective minima of every row in a given 2d matrix

[Jared Smothermon]

Heinz,

M=rand(3,2)
min(M,'c')

The 'c' in the min(.) function specifies that you want a column vector, 
which therefore means each element of the vector is found from across 
the rows.

Regards,

jared
