General Form:

sens output_variable
sens output_variable ac ( DEC | OCT | LIN ) N Fstart Fstop

Perform a Sensitivity analysis. output_variable is either a node voltage (ex. v(1) or v(A,out)) or a current through a voltage source (e.g. i(vtest)). The first form calculates DC sensitivities, the second form AC sensitivities. The output values are in dimensions of change in output per unit change of input (as opposed to percent change in output or per percent change of input).
