I have a matrix of dimensions N x M.
Every cell has an integer.
Now, I want for every 'square', to verify that all its corners are not the same.
Example:
This matrix is fine:
This matrix is not:
The naive solution is to check every possible square, therefore $\binom N2\binom M2$ checks.Is there...
Please Consider :
list={{5,2,6},{2,8,3}}
I need to get the product of all the element within list :
As of now I do this :
(#[[1]]*#[[2]]*#[[3]]) & /@ list
Which means I have to manually specify the number of elements within each least and the sublists length has to b equal.
How cou...
The use of profanity in films has always been controversial, but has increased significantly in recent years. The use of the word fuck in film has always drawn particular criticism; in 2005, the documentary Fuck dealt entirely with this phenomenon. The word fuck is thought to be the taboo term used most in American film.
This is a list of non-pornographic, English language films containing at least 150 spoken uses of the word fuck (or one of its derivatives), ordered by the number of such uses. These are examples of high usage compared to fuck variants used 42 times per million words in...
A common problem in the derivative section of calculus texts is "find the equation of the line that is tangent to the curve $y = \ldots$ at the point $P$."
To find the line that is tangent to $y = 2 x \sin x$ at $(\pi/2,\pi)$, I'd do something like this in Mathematica:
y[x_] := 2 x Sin[x]
y[x] ...
‎Candiru (English and Portuguese) or candirú (Spanish), also known as cañero, toothpick fish, or vampire fish, are a number of genera of parasitic freshwater catfish in the family Trichomycteridae; all are native to the Amazon River. Although some candiru species have been known to grow to a size of in length, others are considerably smaller. These smaller species are known for an alleged tendency to invade and parasitise the human urethra; however, despite ethnological reports dating back to the late 19th century, the first documented case of the removal of a candiru from a human urethra ...
