Convert vector into matrix
mat = vec2mat(vec,matcol)
mat = vec2mat(vec,matcol,padding)
[mat,padded] = vec2mat(...)
mat = vec2mat(vec,matcol)
converts
the vector vec
into a matrix with matcol
columns,
creating one row at a time. If the length of vec
is
not a multiple of matcol
, then extra zeros are
placed in the last row of mat
. The matrix mat
has ceil
(length(vec)/matcol)
rows.
mat = vec2mat(vec,matcol,padding)
is
the same as the first syntax, except that the extra entries placed
in the last row of mat
are not necessarily zeros.
The extra entries are taken from the matrix padding
,
in order. If padding
has fewer entries than are
needed, then the last entry is used repeatedly.
[mat,padded] = vec2mat(...)
returns
an integer padded
that indicates how many extra
entries were placed in the last row of mat
.
Note:

vec = [1 2 3 4 5]; [mat,padded] = vec2mat(vec,3) [mat2,padded2] = vec2mat(vec,4) mat3 = vec2mat(vec,4,[10 9 8; 7 6 5; 4 3 2])
The output is below.
mat = 1 2 3 4 5 0 padded = 1 mat2 = 1 2 3 4 5 0 0 0 padded2 = 3 mat3 = 1 2 3 4 5 10 7 4
