Switch not recognizing that 0 is greater than -1

This always provides an outcome of 1 when plugging 0 for x, when it should be 0^2 or 0

switch x
    case x<-1
        y=1
    case x<=2
        y=x^2
    otherwise
        y=4
end
y =

     1

Read the documentation on switch

Your code make me think you should rather use if, elseif, else, end

[KALYAN ACHARJYA]

Yes it should be , when x=0, then case 1

Again it's easy with if else, as mentioned by @Per Isakson

Answer 1

[the cyclist]

Quoting the Tips section of the documentation for switch:

"A case_expression cannot include relational operators such as < or > for comparison against the switch_expression. To test for inequality, use if, elseif, else statements."

Your case_expression is x<-1, which violates that.

[Walter Roberson]

More accurate is that it is not recommended that case_expression includes relational operators. Whatever the result is of the case expression (even if that is true or false) is going to be compared to the switch value.

x = 0;
switch true
    case x<-1
        y=1
    case x<=2
        y=x^2
    otherwise
        y=4
end

y = 0
