If statement with multiple variables, or if the variables can be shortened.

x is a decimal number always smaller than one based on the users input.

So I want the program to check if the value of a,b,c or d is less than a certain value or greater than, and produce an output.

[Adam Danz]

if 0.6<=a && 0.6<=b && 0.6<=c && 0.6<=d && a<.10 && b<.10 && c<.10 && d<.10
    dime = 1;
end

or

if all(0.6 < [a,b,c,d]) && all([a,b,c,d]<0.10)
    dime = 1
end

Most important, this will never return a true value

all(0.6 < [a,b,c,d]) && all([a,b,c,d]<0.10)

If .6 is less than x, x will always be greater than 0.10.

Answer 2

[Asad (Mehrzad) Khoddam]

if x<1 && x<=0.75
    a = x - 0.75;
elseif x>=0.5
    b = x - 0.5;
elseif x>=2.5
    c = x - 0.25;
else
    d = x;
end
%  make an array of values 
v = [a, b, c , d];
if all(v>0.1) && all(v<=0.6)
    dime = 1;
end
