thank u

for above vector to get 1st element A(1,1)

in scilab array set values in vector form for ex. A=[1 2 3]

scilab program to obtain non fibonacci series

question is
scilab program to find the root of eqn f(x,a)=a*cos(x)-x*e^(-a*x) for different values of a∈[1,10]

i dnt knw hw to insert the condition that a∈[1,10] in newton raphson method

ok....

The spiral has the property that the angle φ between the tangent and radial line at the point (r, \theta) is constant. This property can be expressed in differential geometric terms as

arc cos[(r(θ), r'(θ)/||r(θ)||*||r'(θ)]=arctan(1/b)=⏀

thank you
which is that journal devoted to fibonacci sequence

okay.
then what are logarithmic spirals

no...
