How to plot an equation of this form where the variable has many indices?

Hello,

I'm about to plot constraint equations of an optimization problem. there is an equation as below:

where "y" is a matrix as parameter and "x" is the variable.

I don't have any idea about plotting this type of equation, and it would be much appreciated if you can help me with this.

More information is needed. What is the function x in terms of i,j,k and s?

function?! I think the equation should be considered as an implicit function.

x is a binary variable.
