hi,,lets say I have a matrix,A =[1 0 1 0 0; 10 1 0; 0 0 1 0; 0 0 0 1]. How do I find out that row 3 and 4 has weight one??

How Do I find out a specific weight number in a row of matrix?

I don't understand the question. Specifically,

• You sort of put the question in the title, so it is badly formatted and impossible to interpret
• The matrix A doesn't seem to be a valid matrix at all
• What do you mean by "weight number"?
