You have to add "from future import division" at the top to get the result you want. By default, python2 uses integer division, where for example 1/2 = 0. When you import division from future, the divisions yields floats.
"from future import division" is executed in the spyder console, that's why you see different results.
I have a few remarks about your script:
- you have a "sqrt" without "plt."
- you should import modules at the top of the script
- is there a reason to use matplotlib for numerical functions instead of math (python standard library) or numpy ? Matplotlib is a heavy library to import (lots of graphic stuff).

Spyder Version: 2.2.0 Python Version: 2.7.5 Qt Version: 4.8.4, PyQt4 (API v2) 4.9.6 on Windows
What steps will reproduce the problem?
1.When run the script file using shortkey('F5', i.e. using "runfile" command) What is the expected output? What do you see instead? show much smaller numeric value
Please provide any additional information below
. Hi. I'm graduate student major in biophysics. I've been using this program very usefully. But, recently I encountered some bug. Following is my test code
def stageI(t, k1, k1i, k2, k3): import matplotlib.pylab as plt return -((k1 - k1i - k3)_plt.sinh(1/2_plt.sqrt(k12 + 2_k1_k1i + k1i2 - 2_(k1 - k1i)_k3 + k3*2)t)/plt.sqrt(k12 + 2_k1_k1i + k1i2 - 2_(k1 - k1i)_k3 + k3*2) - plt.cosh(1/2_sqrt(k12 + 2_k1_k1i + k1i2 - 2_(k1 - k1i)_k3 + k32)_t))_plt.e(-1/2_(k1 + k1i + k3)t)
print stageI(11,0.1,1,0.1,0.6)
When I executed this code with 'F5' (thus via "runfile") it gave "7.56298411827e-09". But when execute this code block with F9 or "execfile" it gave 0.646152616418. This later value is correct one (checked with other program like matlab).
Could you fix this bug and, if possible, let me know what is the problem?
Thanks for the reading
