My program is like that

if 2x-5y-6<=0 && 4x-6y+7>=0

........

end

I want a function file for that.

function myprogram(A,b)

I will run it as

>> myprogram([2 -5;4 -6],[6 -7]) How can I specify the inequality signs in the function call

It is the matrix inequality

A*x - b ? 0

where the ? operator may be different for every row and suvadip paul wishes the choice of inequality operators to be user input.

Ya Walter got it right

Walter Roberson 2013-10-5

myprogram([2 -5;4 -6],[6 -7], {'<=', '>='})

I am not clear how to use it.

function myprogram(A,b,?)

An example Please

function myprogram(A, b, user_inequalities)

If you want to figure out which inequality characters were given, use strcmp() or ismember()

Hint: you do not need all four operators. P > Q is the same as -P < -Q
