For each date, use a command like this:

See Steve Lord's answer. If you have a numeric value, you will need to strip off the hours and divide by 100. If you have text, just use a different format - yyyyMMddHH.

If "19940127" is a string, this is much faster than the DATESTR/DATENUM approach:
S = '19940127';
D = [S(5:6), '/', S(7:8), '/', S(1:4)];
If the input is a number, convert it to a string at first:
N = 19940127;
S = sprintf('%d', N);

Is that stored as a number or as text? If it is stored as a number, use datetime with the appropriate ConvertFrom option.
d = 19940127;
dt = datetime(d, 'ConvertFrom', 'yyyymmdd')
If it is stored as text, specify the InputFormat.
d = '19940127';
dt = datetime(d, 'InputFormat', 'yyyyMMdd')
