How to set up an approximately equal conditional statement?
显示 更早的评论
with a tolerance of a certain value like .05, how would I check if the values for example x = 1 and y = 1.02 were approximately equal?

I would do something like this:
x = 1;
y = 1.02;
tol = 0.05;
app_eq = @(x,y,tol) abs(x-y)<tol;
Out = app_eq(x,y,tol)
Out =
1
The result ‘Out’ is a logical value of 1 or true.

What would this tell you?
abs(x - y)

You may wish to look at ismembertol()
Starting in R2024b, you can use the isapprox function to determine if two input arrays are approximately equal. Specify the maximum allowed difference between elements using the AbsoluteTolerance name-value argument.
isapprox(1,1.02,AbsoluteTolerance=0.05)
isapprox(1,1.02,AbsoluteTolerance=0.01)
