syms x
f(x)=4*x^2+20*x+4
fplot(@(x) f, [-10 5])
This is what I've written in octave so far and I keep getting this error:
error: Python exception: ShapeError: Matrix shapes must agree (5, 1) != (4, 1)
occurred at line 3 of the Python code block:
return x.multiply_elementwise(y.applyfunc(lambda a: 1/a)),
error: called from
pycall_sympy__ at line 178 column 7
rdivide at line 104 column 5
interp1 at line 307 column 13
fplot at line 201 column 8
Like, I freaking don't get it. What am I doing wrong? Thanks in advance!
