EXPALS; least squares exponential decay curves. [CDC7600,6600; FORTRAN IV]

Technical Report ·
OSTI ID:6434632
This program fits by least squares a function which is a linear combination of real exponential decay functions. The function is y(k) = summation over j of a(j) * exp(-lambda(j) * k). Values of the independent variable (k) and the dependent variable y(k) are specified as input data. Weights may be specified as input information or set by the program (w(k) = 1/y(k)).CDC7600,6600; FORTRAN IV; SCOPE 2.1; EXPALS requires about 74,062 (octal) words with the maximum number of observations or interpolated values (MMX) set at 200 and the maximum number of values for the lambda calculation (NMX) set at 25.
