Question

0 个投票

hi, i have this problem with matlab. This is my m-file, but it doesnt work.

clear all
t=0:0.1:1;
k=length(t);
a=0;
for i=1:k
    if a==0.8       
        disp('hi')
    end
    a=a+0.1
end
If i use this one
t=0:1:10;
k=length(t);
a=0;
for i=1:k
    if a==8       
        disp('hi')
    end
    a=a+1
end

this one works well. The difference between first and second case is only that some variables are increased 10times. Please help. thank you

Solution:

Here, try this algorithm:

    clear all
    t=0:0.1:1;
    k=length(t);
    a=0;
    for i=1:k
        b = num2str(a);
        if strcmp(b,'0.8');       
            disp('hi')
        end
        a=a+0.1;
    end
