When plotting a np.linspace the figure labeling is not what I wanted
I want to animate julia sets. Anyways everything works so far,
I only need to change the axis labeling. When plotting my values the
x- and y axis are both showing the 500x500 linspace. Id rather like to see
the [-1,1]x[-1,1] Intervall ive defined…

Error using linspace (line 22) Inputs must be scalars
I'm working on fitting a model to data I have collected. Within the model, I identify the optimal parameter values that best fit participant data then adjust and reduce the viewing window (range) to get more precise parameter values. I'm using…

"numpy.linspace" for second time after excluding some point by first "linspace"
I am building a model and I need to get the positions of some points inside a box (known volume). I am thinking on using
a) numpy.linspace(start,stop,30)
b) numpy.linspace(start,stop,3000)
from the same box, I think I need a tool to exclude the…

Is there a similar function in Excel to that of linspace in Matlab?
In Excel, I need to linearly divide 'X' number of cells from value 'A' to value 'B' in 'i' step value. Ideally, I want to achieve the same result as if I was using the linspace function in Matlab.

Rcpp code for "linspace" function: vector length incorrect when increment 1e-5
I want to write a function like "linspace" to create equal interval vectors in R with Rcpp. num_dis here is the number of intervals I want for that vector, i.e., a=0,b=10,num_dis = (10-0)/(1e-5)+1=1000001. When I put linspace(0,10,1000001), the…

curve_fit impossible if the function calls minimize
Say I have a function f1, of an independent variable x and a parameter a.
The function f1, in turn, needs a parameter m that can be obtained minimizing a second function f2, and this function needs the variable x as a parameter.
I have no problem…

Python, interleaving two or more linspace arrays
I have three linspace arrays of equal length: a, b, and c. I want to interleave the arrays together in the following way.
([a[0], b[0], c[0]], [a[1], b[1], c[1]], [a[2], b[2], c[2]], . . . etc.)
I've seen numerous examples of interleaving two or…

Linspace give not exact float
I am trying to define a time vector which is evenly spaced with the numpy linspace function. It looks as following:
t_start = 0
t_end = 0.0032768 # in seconds, equals 3.2768ms
samples = 32768
time = np.linspace(t_start, t_end, samples,…
