代码的预期目标是研究基于Collins积分公式推导C-s-G光束通过理想的和有光阑的FRFT 系统后的光场分布表达式,利用Matlab软件研究FRFT阶数p、光束参数Ω等对输出面光强分布的影响。

好的,这个目标听起来非常有趣和有挑战性。你需要深入研究Collins积分公式、C-s-G光束以及FRFT系统,并理解它们的数学原理。然后,你可以使用Matlab编程来模拟这个系统,并研究FRFT阶数和光束参数对输出面光强分布的影响。这项工作需要一定的数学和编程能力,但如果你能成功,这将是一项非常有价值的研究。祝你好运!

用python代码生成一个图书管理系统
好的,我可以给您提供一个基本的图书管理系统的Python代码,但是需要注意的是,这里提供的是一个简单的示例,实际应用中需要根据具体需求进行修改和完善。
```python
class Book:
def __init__(self, title, author, ISBN):
self.title = title
self.author = author
self.ISBN = ISBN
self.borrowed = False
class Library:
books = []
def add_book(self, book):
self.books.append(book)
def search_book(self, title):
for book in self.books:
if book.title == title:
return book
return None
def borrow_book(self, title):
book = self.search_book(title)
if book is not None and not book.borrowed:
book.borrowed = True
print(f"{title} has been borrowed.")
return True
else:
print(f"{title} is not available for borrowing.")
return False
def return_book(self, title):
book = self.search_book(title)
if book is not None and book.borrowed:
book.borrowed = False
print(f"{title} has been returned.")
else:
print(f"{title} is not a valid book to return.")
if __name__ == '__main__':
library = Library()
book1 = Book("The Hunger Games", "Suzanne Collins", "9780439023481")
book2 = Book("To Kill a Mockingbird", "Harper Lee", "9780446310789")
book3 = Book("1984", "George Orwell", "9780451524935")
library.add_book(book1)
library.add_book(book2)
library.add_book(book3)
print("Welcome to the library!")
while True:
print("What would you like to do?")
print("1. Search for a book")
print("2. Borrow a book")
print("3. Return a book")
print("4. Exit")
choice = input("Enter your choice: ")
if choice == "1":
title = input("Enter the title of the book: ")
book = library.search_book(title)
if book is not None:
print(f"{book.title} by {book.author} with ISBN {book.ISBN}")
else:
print(f"{title} is not available in the library.")
elif choice == "2":
title = input("Enter the title of the book: ")
library.borrow_book(title)
elif choice == "3":
title = input("Enter the title of the book: ")
library.return_book(title)
elif choice == "4":
print("Goodbye!")
break
else:
print("Invalid choice. Try again.")
