Convert equations to MATLAB code

% Equation 1
Vi(k+1)=w*Vi(k)+c1*r1(Xi,best(k))+c2*r2(Xg,best(k)-Xi(k))

% Equation 2
Xi(k+1)=Xi(k)+Vi(k+1)

% Equation 3
w(k)=wmax-(wmax-wmin)/Niter

Answer 1

Last two equations are already in Matlab form, may be just required (.) dot in equation 3 depending on type of variable (if any vector dot operation).

In first equation best(k) menas?

[Tauqeer Nadeem]

Please convert these into matlab code.

[Walter Roberson]

The equations are already in MATLAB form under the assumptions:

1. That indexing starts at 1
2. That w, c1, c2, wmin, wmax, Niter are all scalars
3. That r1 and r2 are each functions that expect a vector for the first argument and a scalar for the second argument, and return scalar values

If k is not a scalar then it is questionable whether correct results would be calculated, but it would not be a MATLAB error.

There are also some circumstances that violate the second and third assumptions in which the code could be valid.

Equation 1

Equation 2

Equation 3

someone convert the above equations to matlab code please.

[KALYAN ACHARJYA]

For 2 ans 3 eqns you already did the same. For eq 1 more clarification needed about Xi,best(k)

[Tauqeer Nadeem]

But how can I write in matlab ? need help on that

[Walter Roberson]

You already wrote them in MATLAB form, provided that the three conditions I mentioned hold. If any of those three conditions do not hold, you have to tell us more details.
