How to convert a text file into an array

I have a text file that looks something like this:
.2668067E-02 .2663488E-02 .2662231E-02 .2662557E-02 .2667599E-02
.2677025E-02 .2674504E-02 .2649519E-02 .2634860E-02 .2667714E-02
.2739410E-02 .2760168E-02 .2696653E-02 .2616312E-02 .2589599E-02
.2655084E-02 .2721280E-02 .2773444E-02 .2776801E-02 .2739715E-02
.2719981E-02 .2739942E-02 .2674718E-02 .2535300E-02 .2691837E-02
.3064602E-02 .3193767E-02 .2785211E-02 .2263564E-02 .2276346E-02
.2812114E-02 .3083767E-02 .2638711E-02 .2749027E-02 .3258084E-02
.3323313E-02 .2719941E-02 .2265815E-02 .2885909E-02 .3676279E-02
.3445298E-02 .2656125E-02 .2620043E-02 .3395507E-02 .3674076E-02
only with many thousand more data points. The data reads from left to right, then steps down to the next row. I am trying to read this text file into a single array (i.e. - I need a 5000 X 1 matrix, not a 1000 X 5 martix)
It would be unreasonable for me to try and manipulate the text file into a single column. Any help would be greatly appreciated. Thanks!
Edit: The following is an example of what I am trying to accomplish
Here is a text file that I am reading
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
and I'm trying to convert it into an array that looks like this
1
2
3
4
5
6
7
8
9
10
11
12

My pleasure!
The reshape function reshapes a vector or matrix into the form you want it. The number of elements in the argument and result arrays must be equal, but that is the only restriction.
Here, it works just as you want it to:
A = [1:5; 6:10; 11:15]
Ar = reshape(A', [], 1)
A =
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
Ar =
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
Notice that you have to transpose the matrix in the reshape call.
