This command allows to calculate the average and standard deviation for data set <ik>. The area used for the calculation can be given by <xmin>,<xmax> for 2d data or <xmin>,<xmax>,<ymin>,<ymax> for 3d data. If these parameters are omitted, the complete actual plotting range is used for the calculation.
The results are stored in the res[i] variables in the following order:
3d 2d -------------------------------------------------------- res[0] res[0] = Number of stored values res[1] res[1] = average of x-values res[2] res[2] = average of y-values res[3] = average of z-values res[4] res[3] = standard deviation of x-values res[5] res[4] = standard deviation of y-values res[6] = standard deviation of z-values res[7] res[5] = # points used for calculation res[8] res[6] = used range : xmin res[9] res[7] = used range : xmax res[10] = used range : ymin res[11] = used range : ymax
