How to solve a combined set of linear equations and inequalities in Matlab?
I have a problem that involves a system of linear equations and inequalities. The problem is defined by Ax = 0 and Cx > 0 (A and C are matrices, x is a vector of variables to be solved for). This problem likely has a range of solutions. I'd like to…

How to use inequalites in cmd code
I was making a code to find square roots for practice with basic cmd coding. However, when I type in a negative number, or an imperfect square, then it goes in an infinite loop. I know how to fix it, but I need to be able to use inequalities( Less…

How to write an inequality in R
Sorry, I am an R newbie and I am having some difficulty
How would I write the following inequality in R:
x > 10 is twice more likely than x < 10
I tried this function and it didn't work :
X = 10
f = function(X,Y) {
if ((2(X) >= 10 & X <= 10) {…

fmincon with nonzero inequalities constraint
I want to solve a minimization problem in MATLAB.
fmincon():
x = fmincon(fun,x0,Aeq,beq, nonlcon) subjects to the nonlinear inequalities c(x) defined in nonlcon such that c(x) < 0
Is it possible to change c(x) < 0 to c(x) ≤ 0 and use…

How to write chained inequalities (a <= b <= c) in if functions
How can you write the following in if functions in R
Supposing you have X ranging from 121 to 212 and Y ranges from 122 to 212, how can you write an if function to represents something like:
if 121 <= X <= 212 and 122 <= Y <= 212; then do…

inequalities issue: 0<=-0.0 is not true
I have an if statement within a for loop which runs through a number values of x and calculates a value of h based on the x. I have included the code below. At time zero (t=0.0) xa=-0.0 and xb =0.0.
The problem arrises when x=0. At x=0 I want the…

Comparing inequalities for Go bigInt?
I am trying to compare two big ints. I'm looking at the docs: https://pkg.go.dev/math/big#Int and I don't see an inequality operator, but I do see an equality one (Cmp).
How am I meant to compare a big int a to a big int b?
Am I meant to subtract b…
