所以我有一个看起来像这样的文件:
# 3 # Number of network ROIs
# 2 # Number of netcc matrices
# WITH_ROI_LABELS
001 002 003
1 2 3
# CC
1.0000 0.9800 0.9895
0.9800 1.0000 0.9817
0.9895 0.9817 1.0000
# FZ
4.0000 2.2965 2.6240
2.2965 4.0000 2.3426
2.6240 2.3426 4.0000
所以我做了以下事情:
file=/users/3dfile1
A= numpy.genfromtxt(file)
m= A[:,:]
m
所以我得到的输出看起来像这样:
array([[ 1. , 2. , 3. ],
[ 1. , 2. , 3. ],
[ 1. , 0.98 , 0.9895],
[ 0.98 , 1. , 0.9817],
[ 0.9895, 0.9817, 1. ],
[ 4. , 2.2965, 2.624 ],
[ 2.2965, 4. , 2.3426],
[ 2.624 , 2.3426, 4. ]])
然而,我的问题是......如果我有多个文件。矩阵大小不一致的地方。这意味着在某些文件中,矩阵将为3x3,某些文件为8x8,1x1等。在这种情况下,我如何编写以下内容:
答案 0 :(得分:1)
尝试
import numpy as np
x = np.array([[ 1. , 2. , 3. ],
[ 1. , 2. , 3. ],
[ 1. , 0.98 , 0.9895],
[ 0.98 , 1. , 0.9817],
[ 0.9895, 0.9817, 1. ],
[ 4. , 2.2965, 2.624 ],
[ 2.2965, 4. , 2.3426],
[ 2.624 , 2.3426, 4. ]])
x1 = x[2:,:]
x2 = x1.reshape(2,3,3)
CC ,FZ = x2
结果:
In [23]: CC
Out[23]:
array([[ 1. , 0.98 , 0.9895],
[ 0.98 , 1. , 0.9817],
[ 0.9895, 0.9817, 1. ]])
In [24]: FZ
Out[24]:
array([[ 4. , 2.2965, 2.624 ],
[ 2.2965, 4. , 2.3426],
[ 2.624 , 2.3426, 4. ]])
