Explain why a stable Grignard reagent cannot be created using an alkyl halide species that contains either a protic group (amino, hydroxyl, thiol, carboxylic acid) or an electrophilic carbonyl functionality (aldehyde, ketone, ester):
The spectrum/auto-correlation of a process is independent of its distribution, and vice versa. Thus, it should be possible to generate a signal where one specifies both its auto-correlation and its distribution. Write a Matlab program that can ge
