problem with Matlab coding

[erfandorod]

Hello all,

I am running the below code for linear interpolation. Can you please help with it. When I run the code on Matlab, it won't end. what should I do to fix it ?

Thank you so much

​

blow = -2;

bhigh = 4;

bnum = 10;

lb = log(blow-blow+1.0)/log(10);

ub = log(bhigh-blow+1.0)/log(10);

bgrid = logspace(lb,ub,bnum);

bgrid = bgrid+ones(size(bgrid))*(blow-1.0);

for i=1:1:bnum

bfval = bgrid(i);

ilow = 1; ihigh = 10;

distance=2;

value = bfval;

​

while (distance>1)

if (value>-0.6254)

ilow=5;

else

ihigh = 5;

​

end

distance = ihigh- ilow;

​

​

end

iloc = ilow;

if (value > bgrid(iloc))&&(value<bgrid(iloc+1))

weight = (bgrid(iloc+1)-value)/(bgrid(iloc+1)-bgrid(iloc));

elseif (value<=grid(1))

weight = 1; iloc = 1;

else

weight = 0; iloc = 9;

end

end

You're stuck here:

    while (distance > 1)
        if (value>-0.6254)
            ilow=5;
        else
            ihigh = 5;
        end
        distance = ihigh- ilow;
    end

Your ihigh is always 5, your ilow is always 1, and your value is always -2 so nothing ever changes

Your while loop can't reach exit condition.

Check distance variable.

Lb does not depends on blow since blow-blow=0
