MATLAB中怎样从矩阵中找出大于1的数,并将这些数排成一个列向量

Answer 1

举个例子
A=random('norm',1,0.5,4,4)

A =

Columns 1 through 3

0.937927825891844 1.33574856680404 1.24444688515589
1.74484880389273 0.396256538657481 1.51734650495893
1.70451724490024 1.35861932566442 1.36344256669162
1.70859620671481 1.81511764458236 0.848279537606992

Column 4

1.14693573354833
0.606358598120681
1.44419781587882
0.426464946515425

>> aa=A(find(A>1))

aa =

1.74484880389273
