3.了解SIMULINK模块库中各子模块基本功能

四、上机练习

1. 学习使用help命令，例如在命令窗口输入help eye，然后根据帮助说明，学习使用指令eye（其它不会用的指令，依照此方法类推）

help eye

EYE Identity matrix.

EYE(N) is the N-by-N identity matrix.

EYE(M,N) or EYE([M,N]) is an M-by-N matrix with 1's on the diagonal and zeros elsewhere.

EYE(SIZE(A)) is the same size as A.

EYE with no arguments is the scalar 1.

EYE(M,N,CLASSNAME) or EYE([M,N],CLASSNAME) is an M-by-N matrix with 1's

of class CLASSNAME on the diagonal and zeros elsewhere.

Example:

x = eye(2,3,'int8');

See also SPEYE, ONES, ZEROS, RAND, RANDN.

x = eye(4,4,'int8')

x =

x=eye(2,3,'int8')

x =

ZEROS Zeros array.

ZEROS(N) is an N-by-N matrix of zeros.

ZEROS(M,N) or ZEROS([M,N]) is an M-by-N matrix of zeros.

ZEROS(M,N,P,...) or ZEROS([M N P ...]) is an M-by-N-by-P-by-... array of zeros.

ZEROS(SIZE(A)) is the same size as A and all zeros.

ZEROS with no arguments is the scalar 0.

ZEROS(M,N,...,CLASSNAME) or ZEROS([M,N,...],CLASSNAME) is an M-by-N-by-... array of zeros of class CLASSNAME.

Example:

x = zeros(2,3,'int8');
