## When to use NNZ in a relational operator?

Use nnz in conjunction with a relational operator to determine how many matrix elements meet a condition. Since relational operators produce logical matrices of 1s and 0s, the nnz function counts the 1s where the condition is true. Create a matrix and determine how many elements are greater than 10.

What kind of model is used for NNZ?

Since nnz is implemented using mixed-integer model. based on a big-M approach, it is crucial that all involved variables have explicit bound constraints. The command should only be applied to integer (or binary) variables.

How is the NNZ operator used in sdpvar?

The nnz operator can be applied to both sdpvar objects and constraints. The following code defines a least-squares problem with integer variables, with the constraints that at most 5 variables are non-zero. As usual, we add explicit bound constraints to enable big-M reformulations.

### Is there a trial version of MATLAB for PC?

You’ll have to cope with using the program in the computer labs of your university or downloading a trial version for students that will provide you with limited access to the program’s functions. Depending on the level of depth with which you thought about making use of the application, you’ll find the demo useful or not.

### Which is the free version of MATLAB r2021a?
