I have a little question. I want to build a matrix in Julia 7.0, where is a concatenation of several vectors of same length. I use the code:
A = rand(10,10)
B = %a empty matrix
B = [B;A[i,:]] %B is the matrix whose line i is from A, where i is odd
In Julia 0.6.4, the above code is ok. But in version 7.0 not run. The error is:
ArgumentError: number of columns of each array must match (got (1, 10))
Anyone could help me?
