of A, except that complex numbers are replaced with their complex conjugates.
How did MATLAB diagonalize this matrix? Here is the thing: The diagonalizable matrices are dense in ! (You probably have heard that before…) What does that mean numerically? Any matrix that you represent in floating point numbers is actually a representative of a whole bunch of matrices. Each...
There are two delimiters in Matlab for making arrays, the comma and the semicolon. The comma separates columns, and the semicolon starts a new row. You can either input a vector as a column vector, or input it as a row vector and then transpose it (like I did with v)....

If y is also in the null space, then Ay= A(Ax)= 0. Finally, if the column space is a subset of the null space, that must always be true: A(Ax)= A2x= 0. Again, in terms of matrices that means A2= 0.FAQ: What Does It Mean When Col A Is a Subspace of t...
