备忘用。 Question I want to create a MATLAB-like cell array in Numpy. How can I accomplish this? Answer Matlab cell arrays are most similar to Pythonlists, since they can hold any object - butscipy.io.loadmatimports them as numpy object arrays - which is an array with dtype=object. To...
>>> a = np.array([[1,2], [3, 4], [5, 6]]) >>> bool_idx = (a > 2)# Find the elements of a that are bigger than 2; # this returns a numpy array of Booleans of the same # shape as a, where each slot of bool_idx tells # whether that element of a is > 2. >>...
举个例子：import numpy as npa = np.array([[1,2], [3, 4], [5, 6]])bool_idx = (a > 2) # Find the elements of a that are bigger than 2; # this returns a numpy array of Booleans of the same # shape as a, where each slot of bool_idx tells # whether that ele...
I have a vector and I want to find out the p-value of the data. In python, linregress(X,Y), gives one of the outputs as p-value. What is the MATLAB equivalent of the same? 댓글 수: 0 댓글을 달려면 로그인하십시오. ...
bool_idx = (a > 2) # Find the elements of a that are bigger than 2; # this returns a numpy array of Booleans of the same # shape as a, where each slot of bool_idx tells # whether that element of a is > 2. print bool_idx # Prints "[[False False] ...

python - numpy/scipy equivalent of MATLAB's sparse function - Stack OverflowS = sparse(i,j,v,m,n) 将 S 的大小指定为 m×n。 等效的python操作是 import numpy as np import scipy.sparse as sps H = sps.csr_matrix((V, (I, J)), shape=(m,n),dtype= np.int32) ...
For MATLAB Online, we need to add the user site packages tosys.pathso Python will find them. usp = py.site.getusersitepackages(); pyrun(["import sys", "if usp not in sys.path: sys.path.append(usp)"], usp=usp); py.sys.path; ...
line) than Matlab code that performs the same task. For code that performs primarily numerical operations, one can expect a Python implementation to be 10 to 20 percent smaller than equivalent Matlab code. For programs that perform extensive string processing, the advantage of Python is even ...
Now that you’re convinced to try out Python, read on to find out how to get it on your computer and how to switch from MATLAB! Note: GNU Octave is a free and open-source clone of MATLAB. In this sense, GNU Octave has the same philosophical advantages that Python has around code ...
