MATLAB: How to show results of for end values as a vector.

arrayfor endvector

Is there any way to represent results of for end as a vector.

for example

for h0=0:1:2
    h=h0*2
end

results

ans
h =
     0
h =
     2
h =
     4

But i want that result like a vector

ans
0  2  4

I know it without using for h0=0:1:2;h=h0*2 . But ı need to represent results of for end as a vector in my real code. can you help

Best Answer

h0 = 0:2;
h = h0.*2

MATLAB: Subscript indices must either be real positive integers or logicals – quick question on how to fix

As I understand your question, you run the code above, then you want to find out values of R_h for some given x value. When you type R_h(25), it'll give you the 25th value of R_h. If you want to find some value of R_h corresponding to an arbitrary value of Response_values, you'll need to interpolate:

Response_values_H= 0:0.01:9;
R_h=zeros(size(Response_values_H));
for n=1:length(Response_values_H)
  rValue_H = Response_values_H(n);
    if rValue_H < 9.1
        R_h(n)=sqrt(4*rValue_H.^2+1)-2*rValue_H;
    else
        R_h(n)=0;
    end
end
plot(Response_values_H,R_h); 
xlabel('Response values') 
ylabel('R_h')
R_h_i = interp1(Response_values_H,R_h,2.5); 
hold on
plot(2.5,R_h_i,'ro','markersize',10)

MATLAB: How to create a three-column matrix that consists of the elements, squares, and cubes of a row vector

There are a couple ways to get the result you want, but the easiest is to simply transpose your ‘H’ matrix before you return it:

H = [v; v.^2; v.^3]';
