# Outer product using CBLAS
I am having trouble utilizing CBLAS to perform an Outer Product. My code is as follows:

Temperature of filament using its area, power, and emissivity

Fluxthroughme
I have entered the emissivity in the calculation so that we can treat it as a blackbody, allowing us to use $I_{tot} = \sigma T^4$. My book tells me the correct answer is $2.06*10^4$, which I'd normally put down to a misprint... | {} |
let's consider a composite natural number $n$ greater or equal to $4$. Goldbach's conjecture is equivalent to the following statement: "there is at least one natural number $r$ such as $(n-r)$ and $(n+r)$ are both primes". For obvious reasons $r\leq n-3$. Such a number $r$ will be called a "primality radius" of $n$.

# How to define a sloping boundary?
As we know, if I want to define a boundary of a box, I can use some codes like"wherezero(x[0])"
On this basis, if I want to define a sloping boundary like the hypotenuse of the triangle，how can I do that?
