MATLAB是一种矩阵语言 MATLAB的文档中写到:MATLAB is a matrix language, which means it is designed for vector and matrix operations. You can often speed up your M-file code by using vectorizing algorithms that take advantage of this design. Vectorization means converting for and while loops to eq...
forandwhileloops that incrementally increase the size of a data structure each time through the loop can adversely affect performance and memory use. Repeatedly resizing arrays often requires MATLAB®to spend extra time looking for larger contiguous blocks of memory, and then moving the array into...
more efficient way of doing loops. This would apply to just basic for loop and while loop problems. Let me know if there is a simple way, but if there is an advanced method please also mention it.
I saw no difference in figures, but your loops may be different because you wrote : "while t<40" which does not include the 40, it self. But "for" contains the upper bound, which is 40. In other word, your first loop is done 4000 times, however, the "for" loop runs 4001 time...
