h = actxserver('DAO.DBEngine.36');
database = 'C:\Users\tV CaLeR\Documents\MATLAB\Maisarah BITD\cm1\data.mdb';
db = h.OpenDatabase(database);
tbl_names = {'data1'};
sql = ['INSERT * INTO ' char(tbl_names(1))];
rs = db.OpenRecordset(sql);
[row,col] = size(rs.GetRows(1));
rs.MoveLast;
ile_wierszy = rs.RecordCount;

The correct expression for an INSERT is:
INSERT table_name
VALUES (value1, value2, ...)
or
INSERT table_name
SELECT field1, field2, ... FROM other_table

rs=invoke(db,'OpenRecordset','Table1');
fieldlist=get(rs,'Fields');
ncols=get(fieldlist,'Count');
for c=1:double(ncols)
fields{c}=get(fieldlist,'Item',c-1);
resultset.columnnames{c}=get(fields{c},'Name');
