Top Forums Shell Programming and Scripting script to iterate Post 302561537 by Tytalus on Tuesday 4th of October 2011 11:29:14 AM

something along the lines of:

Code:
(rewriting your equation to isolate an iteration:

x=y/ln(3.455613x)
)

#  y=1;x=1;for i in {1..100}; do x=$(calc "$y/(log(3.455613*$x))"); echo $x;done
0.806452
0.975715
.
<snip>
.
0.890054
0.890054

where I have calc as a function:

#  typeset -f calc
calc ()
{
    nawk 'BEGIN { OFMT="%f"; print '"$*"'; exit}'
}

In this case, then:

#  calc "log(0.890054)"+1.24
1.123527

#  calc 1/0.890054
1.123527

You may prefer to define an epsilon value and check the diff between successive iterations to define your accuracy.

glgetclipplane

GLGETCLIPPLANE(3G)						   OpenGL Manual						GLGETCLIPPLANE(3G)

NAME

       glGetClipPlane - return the coefficients of the specified clipping plane

C SPECIFICATION

       void glGetClipPlane(GLenum plane, GLdouble * equation);

PARAMETERS

       plane
	   Specifies a clipping plane. The number of clipping planes depends on the implementation, but at least six clipping planes are
	   supported. They are identified by symbolic names of the form GL_CLIP_PLANEi where i ranges from 0 to the value of GL_MAX_CLIP_PLANES -
	   1.

       equation
	   Returns four double-precision values that are the coefficients of the plane equation of plane in eye coordinates. The initial value is
	   (0, 0, 0, 0).

DESCRIPTION

       glGetClipPlane returns in equation the four coefficients of the plane equation for plane.

NOTES

       It is always the case that GL_CLIP_PLANEi = GL_CLIP_PLANE0 + i.

       If an error is generated, no change is made to the contents of equation.

ERRORS

       GL_INVALID_ENUM is generated if plane is not an accepted value.

       GL_INVALID_OPERATION is generated if glGetClipPlane is executed between the execution of glBegin() and the corresponding execution of
       glEnd().
