Simpler and more efficient:

% load your data:
S = load('split_mat.mat');
C = S.split_mat;
% convert to numeric:
F = @(t)sscanf(t,'%f,',[1,Inf]);
D = cellfun(F,C,'uni',0)

D = 79×1 cell array
    {[                   1]}
    {[                   2]}
    {[                 1 3]}
    {[                 2 4]}
    {[                 3 5]}
    {[                 4 6]}
    {[           1 1 1 5 7]}
    {[         1 2 2 2 6 8]}
    {[         2 3 3 3 7 9]}
    {[        3 4 4 4 8 10]}
    {[        4 5 5 5 9 11]}
    {[       5 6 6 6 10 12]}
    {[       6 7 7 7 11 13]}
    {[ 1 1 1 9 10 10 10 14]}
    {[2 2 2 10 11 11 11 15]}
    {[3 3 3 11 12 12 12 16]}
