LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];

T = table(Age,Height,Weight,BloodPressure,'RowNames',LastName)
T = 

                Age    Height    Weight     BloodPressure 
                ___    ______    ______    _______________

    Smith       38     71        176       124          93
    Johnson     43     69        163       109          77

The variable BloodPressure counts as one variable even though it contains two columns.
