Identity theft is not a joke, Jim. Millions of families suffer every year. Also one that the internet gets wrong all the time: “dude, this is a Wendy’s”, not “sir this is a Wendy’s”

I believe it’s actually, “dude, this is a Wendy’s restaurant.” Check and mate.

Thank you OP!

At least they’re symmetric.

Uhh who’s joking about identify theft?

Could one of you scholars please explain the joke for us smoothbrains who don’t get it? All I see is a matrix.

A square matrix with the ones in the diagonal is called the identity matrix

It’s an identity matrix. You multiple a vector with it and the result is still the same (identical) vector

Eigen see how this is confusing, I don’t get it either

That matrix of zeros with one in diagonal is called the matrix of identity.
It is famous because when doing multiplication on matrix or vector, it acts likes 1 on “normal” number: 1 times x is x Identity times anyMatrix is anyMatrix.

Wouldn’t you need to put
anyMatrix
first, since matrix multiplication isn’t commutative?Saleh@feddit.org 1 month ago
You multiply vectors and matrizes row by column.
So for any matrix the fitting identity matrix multiplies each row on the relevant position by one and puts it into a column.
The matrix remains the same.
