以下是printmat的略微修改版本，可以打印复数。随意摆弄一下以获得更好的外观:)

function [] = printmat2(a,name,rlab,clab)

%PRINTMAT Print matrix with labels.

% PRINTMAT(A,NAME,RLAB,CLAB) prints the matrix A with the row labels

% RLAB and column labels CLAB. NAME is a string used to name the

% matrix. RLAB and CLAB are string variables that contain the row

% and column labels delimited by spaces. For example, the string

%

% RLAB = 'alpha beta gamma';

%

% defines 'alpha' as the label for the first row, 'beta' for the

% second row and 'gamma' for the third row. RLAB and CLAB must

% contain the same number of space delimited labels as there are

% rows and columns respectively.

%

% PRINTMAT(A,NAME) prints the matrix A with numerical row and column

% labels. PRINTMAT(A) prints the matrix A without a name.
