pulpy.grad.waveform.min_trap_grad

pulpy.grad.waveform.min_trap_grad(area, gmax, dgdt, dt)

Minimal duration trapezoidal gradient designer. Design for target area under the flat portion (for non-ramp-sampled pulses)

Parameters:

• area (float) – pulse area in (g*sec)/cm

• gmax (float) – maximum gradient in g/cm

• dgdt (float) – max slew rate in g/cm/sec

• dt (float) – sample time in sec

Returns:

2-element tuple containing

• trap (array): gradient waveform in g/cm.

• ramppts (int): number of points in ramps.
