I can not write text on an image by insertText

4 views (last 30 days)
I have been trying to write text on generated figure using the insertText function. Even when using the following example code given in the Mathworks website:
position=[1 50; 100 50];
value=['55' '66'];
and I keep getting the error:
Error using +
Invalid type of input arguments (should be uint64)
Error in insertText>populateGlyphBuffer_sim (line 832)
thisValue = uint16(fontHashTable.Count+1);
Error in insertText (line 146)
Error in Untitled5 (line 4)
I've changed the format of figure from uint8 to uint 16 but it doesn't help. Is there any mistake I missed? or is it the version issue? I'm using 2021b Matlab.

@Walter Roberson I'm experiencing the same issue.
Map with properties:
Count: 0
KeyType: char
ValueType: uint16
ans =
typecast(fontHashTable.Count, 'uint8')
ans =
1×8 uint8 row vector
0 0 0 0 0 0 0 0

@Xiaoai Chen - should the value input parameter be a cell array of strings rather than an array? Please see text (of insertText0 for details.
