MATLAB: How to find minimum value from loop using if function iteration

for loopif statementnested function

I have a=6.5, I would like to define "if function" inside the "for loop", for i=1:10, it will do the loop imin < a < imax, and if the "if function" is correct, I would like to use the b= imin (in which the a function is correct).
My expectation toward the code is b=6. Since the 6.5 is in between number for loop 6 and 7. And I want to use 6 (imin where the a is in correct statemen for if function)
How do I code that in matlab?
a=6.5;
for i=1:10
    imin=i;
    imax=imin+1
    if imin<a<imax
        b=imin;
    end
    if imax==10;
    end
end

Best Answer

>> a = 135500;
>> dx = 1000;
>> b = floor(a/dx)
b =  135
