Bessel Functions of the First and Second Kinds
• J0(z)—Returns the value of the zeroth order Bessel function of the first kind.
• J1(z)—Returns the value of the first order Bessel function of the first kind.
• Jn(m, z)—Returns the value of the mth order Bessel function of the first kind.
• Y0(z)—Returns the value of the zeroth order Bessel function of the second kind.
• Y1(z)—Returns the value of the first order Bessel function of the second kind.
• Yn(m, z)—Returns the value of the mth order Bessel function of the second kind.
The scaled versions have a scale factor of e−|Im(z)|. Type sc as a literal subscript after the function name to specify the scaled function J0sc(z).
These functions, and their scaled versions, can be evaluated both numerically and symbolically.
Arguments
• m is a real number or vector.
• z is a dimensionless complex scalar or vector. For Y0, Y1, Yn and their scaled versions, z ≠ 0.
• If both m and z are vectors, then they must be of equal lengths.
