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.

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.

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
