MATLAB Online에서 열기 I want to create a matrix of x and y coordinates . I want to get that from a figure so I'm using a ginput value to get one point and the other point is a constant . Now , by doing the linespace command of say 5 members...
I am working on a quantum mechanics problem and would like to get a 4x4 matrix A into diagonal form such that A=UDU^{-1}. Basically I just need to know the values of D and U required in the expression to make A a diagonal matrix (where D is diagonal) as I can then use it to...
Learn how to create a matrix that has an underlying pattern in a for loop, as well as how to use preallocation for the same process.

Your x and y values that come out will be vectors that are scattered around, not a regular grid. You can only use mesh() when the x and y represent grids. If you want a gridded surface then you should look at triscatteredinterp() or the newer griddedinterpolant()In...
If you want to generate uniformly distributed random numbers, you can use the rand() function in MATLAB, which generates random numbers between 0 and 1. You can also specify the size of the matrix containing random values, and each value will be between 0 and 1, which you can scale accor...
So what I now want to do with these 2 matrices is make matrix y point to matrix x, and return the values in x to y. Meaning matrix y tells me that the specific value I want is in columns 1 and 2, now I want to tell matrix y to look at matrix x, and see that f...
Are all different and all have columns and rows that sum to the same values. I would take this, above information, do something with it to make MATLAB's magic square randomized and then use it to index into x.Thanks
I use "allcomb.m" to create something like all the possible numbers that are between 0 and 100, with intervals of 5. However, this matrix is so big, and that implies that Matlab doesn't create it. I was thinking that, if I have that matrix, I could reduce it using a condition but...
