Length/Index based if else statements

I have a vector of variable length, for example
b = [0.25;0.5;0.75;1;1.5;1.75;2.0];
and based on the length of this vector, I have some specific parameter K against each element of b, x is the input and my final output is m
if x < b(1)
m = K(1);
elseif x < b(2)
m = K(2);
elseif x < b(3)
m = K(3);
elseif x < b(4)
m = K(4);
elseif x < b(5)
m = K(5);
elseif x < b(6)
m = K(6);
else
m = K(7);
end
I want to generalize my code based on the length of b. Here, the length was 7 so I had to run it manually like this for 7 elements. How can I generalize this for any length of b?

idx = find(x < b,1);
if isempty(idx)
idx = numel(b);
end
m = K(idx);
The above assumes b is sorted in ascending order, as in the example. If b is not necessarily sorted, you'd have to sort it first.

Dear
Have you solved this problem? I met the error recently.
compilation of model failed while trying to resolve underspecified signal dimensions
