在研究opencv，不是很难，但是需要换种思维来认知这个C/C++为编程函数的开源代码库，OK，我现在还是总结一些常用MATLAB的函数，随时更新，下一阶段就是opencv方面的认知了！

1.std

Standard deviation

Syntax

    s = std(X)

    s = std(X,flag)

    s = std(X,flag,dim)

Examples

For matrix X

    X =

    1 5 9

    7 15 22

    s = std(X,0,1)

    s =

    4.2426 7.0711 9.1924

    s = std(X,0,2)

    s =

    4.000

    7.5056

 

2.reshape

Reshape array

Syntax

    B = reshape(A,m,n)

    B = reshape(A,[m n])

    B = reshape(A,m,n,p,...)

    B = reshape(A,[m n p ...])

    B = reshape(A,...,[],...)

Examples

Reshape a 3-by-4 matrix into a 2-by-6 matrix.

    A =

    1 4 7 10

    2 5 8 11

    3 6 9 12

    B = reshape(A,2,6)

    B =

    1 3 5 7 9 11

    2 4 6 8 10 12

    B = reshape(A,2,[])

    B =

    1 3 5 7 9 11

    2 4 6 8 10 12
