A = randi(1800,801,3);% A - Let your matrix.
A1 = A(1:end-1,:); % for this is case - size of A - [801x3]
outDouble3d = permute(reshape(A1.',3,100,[]),[2 1 3]);
or
outCell = mat2cell(A,[100*ones(fix(size(A,1)/100),1);1],3)
ADD
n = 89;
[m,k] = size(A);
t = rem(m,n);
if ~t, t = []; end
outCell = mat2cell(A,[n*ones(fix(m/n),1);t],k)

thanks a lot ; but another problem is show : when i change 100 to another number as 89 this error appear :
_Error using ==> mat2cell at 116 Input arguments, D1 through D2, must sum to each dimension of the input matrix size, [801 3]. _
