Hi,
I have 4 dimentional hypermat in scilab. two things I want to do but I have problems.
1.I want to extract data from 1 dimension of the hypermat. for example a=A(1,1,:,3). I got a hypermat (1,1,N,1). How can I reduce the size to (1,N) or (N,1).
2. I use save command to store the hypermat in a file and I can read by load. I also want to export data to matlab but I couldnt use savematfile for hypermat. DO yo have any suggestion to save hypermat in format matlab can read?
Thanks in advances,
Thang Pham

a=matrix(a,1,N)
a=A.entries;
d=A.dims;
savematfile /tmp/foo.mat a d
in Matlab
load /tmp/foo.mat
A=reshape(a,d)

you can use the matrix function (similar the Matlab reshape function)

If A is your hypermat you can do in Scilab:
a=A.entries;
d=A.dims;
savematfile /tmp/foo.mat a d
in Matlab
load /tmp/foo.mat
A=reshape(a,d)
