MATLAB: If statement problem

if statementMATLAB

Hello, I'm having some problems with an if statement. This is what I want to do: If x>1 A=B elseif x<1 and x>0.1 A=C elseif x<0.1 and x>0.01 A=D elseif x<0.001 A=F
I don,t seam to be able to get this working. Any help is welcome
Here is the code:
Y=random('unif',0.01,2,100,1);
for i=1:100
    if Y(1:i,1)>=1
        c(i,1)=1;
        c(i,2)=0; 
        c(i,3)=0;
    elseif (Y(1:i,1) < 1) && (Y(1:i,1) >= 0.1)
        c(i,1)=1;
        c(i,2)=0.5;
        c(i,3)=0; 
    elseif (Y(1:i,1)<0.1) && (Y(1:i,1)>=0.01)
        c(i,1)=1;
        c(i,2)=1;
        c(i,3)=0;
    elseif Y(1:i,1)<0.01 
        c(i,1)=0;
        c(i,2)=1;
        c(i,3)=0;
    end
end

Best Answer

You should use:
Y(i,1)
instead of
Y(1:i,1)
Also preallocate c:
c = zeros(size(Y,1),3);
You can simply write:
if Y(i,1) < 0.01
    ...
elseif Y(i,1) < 0.1
    ...
elseif Y(i,1) < 1
    ...
else
    ...
end
