Syntax
oneTrue(b);
Description
Returns true if exactly one element of the input Boolean vector b is true. Otherwise the function returns false. If b is an empty vector, i.e., size(b,1)=0, the function returns false.
Example
Boolean b1[3] = {false, false, false};
Boolean b2[3] = {false, true, false};
Boolean b3[3] = {false, true, true};
Boolean r1, r2, r3;
algorithm
r1 = oneTrue(b1); // r1 = false
r2 = oneTrue(b2); // r2 = true
r3 = oneTrue(b3); // r3 = false
