Toronto function

In mathematics, the Toronto function T(m,n,r) is a modification of the confluent hypergeometric function defined by Heatley (1943), Weisstein, as

T(m,n,r)=r^{2n-m+1}e^{-r^{2}}{\frac {\Gamma ({\frac {1}{2}}m+{\frac {1}{2}})}{\Gamma (n+1)}}{}_{1}F_{1}({\textstyle {\frac {1}{2}}}m+{\textstyle {\frac {1}{2}}};n+1;r^{2}).

Later, Heatley (1964) recomputed to 12 decimals the table of the M(R)-function, and gave some corrections of the original tables. The table was also extended from x = 4 to x = 16 (Heatley, 1965). An example of the Toronto function has appeared in a study on the theory of turbulence (Heatley, 1965).
