在Scilab上，你可以使用read函数，它读取格式化的文本文件，你至少需要知道列数。要增加垂直间距，你应该为每一整列增加一个常量值i*d，其中i是列数。
我把你给的例子放在一个文本文件里，这样我就可以阅读它，然后我把它画出来。

//read(): first argument is file path 
//        (or file name, if you change current directory)
//        second argument is number of lines (-1 if unknown)
//        third argument is the number of columns
B = read("file.txt",-1,6);

d  = 1000; //vertical spacing
Bs = B;    //copy of the original data

for i = 1 : size(Bs,'c')
    //loop adding constant to each column
    Bs(:,i) = Bs(:,i) + (i-1) * d;
end

//simply plot the matrix
plot2d(Bs);

Scilab中的结果为：

MATLAB语言
在MATLAB中，你可以使用importdata函数，它也可以读取格式化的文本文件，但至少需要文件名。你还应该手动添加垂直间距。

%call importdata() after changing current directory
B = importdata("file.txt");

d  = 1000; %vertical spacing
Bs = B;    %copy of the original data

for i = 1 : size(Bs,2)
    %loop adding constant to each column
    Bs(:,i) = Bs(:,i) + (i-1) * d;
end    

%plot the modified matrix
plot(Bs);

MATLAB中的结果为：
