Hello. I can't understand. Why does it turn out 4 roots or not 2? Thanks.

Hi. Because that's how what might be called "scalar expansion" for sys() works. Perhaps the result you are looking for is this using vectorize()



Best regards.
Alvaro.

Thanks!

How it is better to set then an array of the data? Need to get a solution for some data (for example: values a 4, 5, 6, 7...)
Matrix didn't work either.

Hi. Supposedly, vectorize operates only on matrices.

It should have worked. Do you have an example of how it didn't work?

Visit the Samples ... find zillions of examples.

You can use range() functions.
