To fix this issue In what environment are you running this? With Windows command line I get:
code :
>>> x = Matrix(4, 3, range(12))
>>> r=x.applyfunc(lambda e: 
... Decimal(str(round(e+.2,1))).quantize(Decimal('.01'), 
... rounding=ROUND_HALF_UP))
>>> r[0]
>>> r
[0.2,  1.2,  2.2],
[3.2,  4.2,  5.2],
[6.2,  7.2,  8.2],
[9.2, 10.2, 11.2]])
>>> r[0].round(1)

wish helps you Working with a sympy Matrix or numpy array of sympy symbols, how does one take the element-wise logarithm? , Use Matrix.applyfunc:
code :
In [6]: M = sympy.Matrix(sympy.symbols('a b c d'))

In [7]: M.applyfunc(sympy.log)
⎢      ⎥
⎢      ⎥
⎢      ⎥

seems to work fine Given the product of a matrix and a vector , The git version of SymPy (and the next version) handles this better:
code :
In [55]: print(diff(C[l,h], A[i,j]))
Sum(KroneckerDelta(_k, j)*KroneckerDelta(i, l)*B[_k, h], (_k, 0, m - 1))

hop of those help? To be more specific, I want to apply the following sigmoid function:
code :
>>> M.applyfunc(sigmoid)

[1/(exp(-1) + 1), 1/(exp(-3) + 1)],
[1/(exp(-2) + 1), 1/(exp(-4) + 1)]])
class sigmoid(Function):
>>> M.applyfunc(sigmoid)
[sigmoid(1), sigmoid(3)],
[sigmoid(2), sigmoid(4)]])

wish helps you After calling sqrtm type of matrix changed and you can not use evalf:
code :
from sympy import *
from mpmath import *
[2.0  1.0  0.0]
[1.0  2.0  1.0]
[0.0  1.0  2.0]

To fix this issue As we know , Why you do not use method evalf with args like evalf(3)?
code :
from sympy import *

x = sin(pi/4)
y = sin(pi/5)

A = Matrix([x, y])

Matrix([[0.707], [0.588]])
