Essentially i only have A=9x1 and x=1:7. B is the resulting values of A*x and they are given as 9 different values which is what i need. Basically i need a loop to run through the caluclation of A*x=B until a single value of the 9 given by B is over 60. once any of said values hits 60 i need the loop to stop and display all 9 B values that are accepted and the x value that gives these B values that are less than the tolerance of 60. Ive attached a screenshot of what i have so far. However, it just runs through the loop without stopping when the B values i want to limit to are exceeded.

Do not share screenshot but use the CODE environment

If b is a vector, b > 0 is a vector of logical values. If you need to check if only one of the entry of b is larger than 0, use

if any(b>0)

Another thing is not proper in your code: the matrix A does not depend on m and it is constant through the iterations: you can move it outside the loop along with the statement w = 1;
