No InputFormat 'YYMMDD' found for datetime

Is there a way to transform '240331' into '31 March 2024' ?

The following does not work:

datetime('240331',InputFormat,'YYMMDD')

Unrecognized function or variable 'InputFormat'.

Character case matters!

"Is there a way to transform '240331' into '31 March 2024' ?"

datetime('240331', 'InputFormat','yyMMdd', 'Format','dd MMMM yyyy')

ans = datetime
   31 March 2024

Thanks a lot @Stephen23!! :-)

Either leave the quotes off but use == (if you're using a sufficiently recent release) or add quotes. You will need to adjust your format specifier, though.

datetime('240331',InputFormat = 'yyMMdd')

ans = datetime
   31-Mar-2024

datetime('240331','InputFormat','yyMMdd')

ans = datetime
   31-Mar-2024

You need to use 'yy' instead of 'YY' and 'dd' instead of 'DD'.

datetime('240331',InputFormat = 'YYMMDD')

Error using datetime (line 669)
The format 'YYMMDD' contains an unsupported symbol: 'Y'. See the datetime.Format property for a complete description of the identifiers used in datetime formats.

Many thanks to both of you @Steven Lord and @Star Strider!

Very appreciated! ...I thought that the input format was not case sensitive... :-)

Please, bear in mind that I would have accepted both of your answers, if I could! :-) :-)

Since the format needs to have ways to represent both the Month component and the minute component of a datetime, the most natural representation IMO is for M to be case sensitive. [This was not a choice MathWorks made; that's part of the Unicode Locale Data Markup Language specification linked from the documentation page I reference below. I believe the LDML uses the symbols from ISO standard 8601.]

The table in the entry for the Format property on the datetime documentation page lists the character and character sequences that have special meanings when used in a format specifier (either the InputFormat name-value argument to the constructor or the Format property which can be set in the constructor or after the object has been created.)

Wow, nice explanation, thanks! I will read about the document page :-)
