〜= Matlab中的运算符

Question

Does anyone know what the operator ~= in Matlab? I have seen it in an if statement

if currsign ~= 0
[

]

Not equal to?

Answer 1

It simply means "not equal"

For example:

1 ~= 1 % Returns false

1 ~= 2 % Returns true

Answer 2

In Matlab ~= is not equal to. the brackets following the if are not valid Matlab syntax though. 'if' needs to be paired with an 'end'
