comparison of two column vectors

sir/madam i have two column vectors, i want to compare element by element and want to know which is large or small.

please help me, how can i write command for it.

Answer 1

[per isakson]

An example

%%
v1 = rand( 6,1 );
v2 = rand( 6,1 );
%%
v1 > v2

ans = 6×1 logical array
   1
   0
   0
   1
   1
   1

This result tells us that the first, fourth, fifth and sixth element of v1 are larger than the corresponding elements of v2

@pramod kumar it would benefit you to invest two hours here:

after that you'll be able to answer questions like this, and many more, yourself.

@per isakson sir, if i am comparing the v1 and v2, for the element logical array is showing 1, i have to write V vector. For thi case how can i proceed the loops.

if v1<=v2 % If linear

V= K*u;

else % If nonlinear

V=K*u;

end

I don't understand your comment.

Read if, elseif, else, Execute statements if condition is true and please notice: An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric).

@per isakson SIR,

I want to write coding for the element of LV having zero or One .

how can wrote for that specific element.

Example,

for n=1:1:5
    for LV=v1<=v2  % v1 v2 are column vectors
        if LV==1
            Fs= xyz;  % for that element of LV which have one
        else
            Fs=abc;  % for that element of LV which have zero
        end
    end
end 

It will work sir?

@per isakson sir, please suggest me.

[per isakson]

No it will not work. Why don't just try to run it?

Did you spend a couple of hours with MATLAB Academy - Free 2 hour training ?

Why do you have two for-loops. One should be enough.

In a statement like, for LV=v1<=v2, the expression, v1<=v2, must evaluate to a row. See help on for-else-end.

In the assignment, Fs=abc;, Fs is overwritten each time LV is false.

@per isakson @Michael Kleder @Matt J Sir the real problem is, I have 2 type of Column vector of 6X1

F_s1=(1;5;7;4;6;8)

F_s2=(0;5;8;3;7;7)

and

F_r1=(0;1;5;7;4;3)

F_r2=(1;2;11;1;5;9)

sir i have to compare F_s <= F_r each elemet one by one and which satisfy the condition for that some other actions i have to take. So suggest me how can i do it element by element not a complete one.

please @per isakson sir, suggest me how can i compare element by element?
