gives the inverse bilateral Laplace transform of expr.
gives the multidimensional inverse bilateral Laplace transform of expr.
Details and Options
- The inverse bilateral Laplace transform of a function is defined to be , where the integration is along a vertical line , lying in a strip in which the function is holomorphic. In some cases, the strip of analyticity may extend to a half-plane.
- The multidimensional inverse bilateral Laplace transform of a function is given by a contour integral of the form .
- The integral is computed using numerical methods if the third argument, , is given a numerical value.
- The following options can be given:
AccuracyGoal Automatic digits of absolute accuracy sought Assumptions $Assumptions assumptions to make about parameters GenerateConditions False whether to generate answers that involve conditions on parameters Method Automatic method to use PerformanceGoal $PerformanceGoal aspects of performance to optimize PrecisionGoal Automatic digits of precision sought WorkingPrecision Automatic the precision used in internal computations
