Pass a Previous Value to function MATLAB
I have the following function:
y(t) = alpha*y(t-1) + beta*y(t-1) + delta
where alpha,beta, and delta are constants.
I am assuming that y(0) = 0. I'm trying to create a MATLAB function to represent y(...

MATLAB Error using fzero
y = @(Er) i*sqrt((((w^2*Mr*(Er))/isik_hizi^2)-(2*pi/lamdac)^2));
y0 = i* sqrt((w/isik_hizi)^2-(2*pi/lamdac)^2);
yansima = @(Er) ((y0/m0)-(y(Er)/m))/((y0/m0)+(y(Er)/m));

How to iterate over functions?
I would like to apply loop over a function. I have the following "mother" code:

fun = @root;
x0 = [0,0]
options = optimset('MaxFunEvals',100000,'MaxIter', 10000 );
x = fsolve(fun,x0, options)

Matlab function argument issue
hey I have a function defined as,
drift = @(x1,x2,u)[x2,(a*sin(x1) - b*x2 + u)]*.05;
then I attempt to call it while in a triple for loop (iterating over
x1= 1:length(n1),
x2 = 1:length(n2)
x3 = 1:...

Matlab loops for a function
I am trying to make a loop to redo a Matlab function 1000 times. Here's the program
d = unifrnd (0,10,[10,1]);
c = d.^(-2);
a = round(unifrnd(0,1,[1,10]);
e = a*c
btotal = e+1
SIR = 1/btotal
What I ...
