显示 更早的评论
Can someone help me with this homework? I'm extremely new to MATLAB and have no idea how to do this.
1)Solve the equation Ax=b and answer the following questions
Where A=[1 2 3 4; 4 2 3 1; 4 3 1 5; 4 3 2 5]
b=[1; 2; 3; 4]
a)What are the dimensions of the x vector?
b)What is the solution vector?
2)Using the same A calculate A-transpose
a)What are the dimensions of A-transpose?
b) What i the A-transpose vector?
THANK YOU!

Reading the Getting Started chapters of the documentation is a good idea. All necessary basics are explained there.

Hint: look up the size() function. And I'm sure if you looked up transpose in the help you'd find the apostrophe operator. A transposed would be another array, not a vector.

A=[1 2 3 4; 4 2 3 1; 4 3 1 5; 4 3 2 5];
b=[1; 2; 3; 4];
x = b/A
size(x)
P = A';
