just the last part is important. i think there is something wrong with my use of fzero.. when i want to calculate this, i get this error: 테마복사 >> theta(2) ??? Error using ==> fzero at 181 If FUN is a MATLAB object, it must have an feval method. Error in ==>...

Part of the book series: Graduate Texts in Mathematics ((READMATH,volume 123)) 3226 Accesses Abstract There are many possible ways of introducing the number π, associated with the circle. We shall obtain π from the complex exponential function expz=1+z2!+⋯. . ...
You may see ex written exp(x), treated like any other function f(x). Here, x is just a numerical input to an intricate power series. Concepts like repeated counting, growth rate, and time fall into the background (though we can see them if we look). Curiously, we're left with...
Thus, a grow- ing body of literature suggests that synaptic loss and dysfunction and network disruptions, rather than con- ventional pathological hallmarks, are main players in the development of cognitive decline in AD. Multifactorial etiologies of AD AD is a complex disease caused by the ...
Functional analyses have addressed them independently, and this approach has resulted in many suppositions that this report will define and question. Alternatively, cardiac muscle mass is formed by the helix and surrounding circumferential wrap described by Lower in the 1600s [1], Senac in the ...
Therefore the result of a floating-point calculation must often be rounded in order to fit back into its finite representation. This rounding error is the characteristic feature of floating-point computation. The section Relative Error and Ulps describes how it is measured. ...
The Least Common Multiple (LCM) is the smallest or least common multiple that two or more numbers have in common. Finding the LCM helps us determine a common...
Partial wave spectroscopy takes advantage of the field effect to allow for the sensitive and specific detection of cancers in tissues that are difficult to reach. Cancer is an extraordinarily complex disease. Methods that are commonly used in physics can reduce the complexity of cancer to a ...
