Hi all. I cannot set the 'Table" by using set_param

my_data = [1 1 1 1];
set_param(char(my_table),'Table',my_data)
Invalid setting in Lookup_n-D block 'table_xyz' for parameter 'Table'  
my_data = [1 1 1 1];
set_param(char(my_table),'Table',num2str(my_data))
Parameter 'Table' setting: "1  1  1  1" cannot be evaluated.
Caused by:
  Error: Unexpected MATLAB expression.
my_data = [1 1 1 1];
set_param(char(my_table),'Table',{my_data})
Invalid setting in Lookup_n-D block 'table_xyz' for parameter 'Table'

On the other hand, by using numerical value, e.g.

my_data = [1 1 1 1];
set_param(char(my_table),'Table','[1 1 1 1]')

It works. any thoughts?

在 MATLAB Online 中打开

Assuming mydata is a row vector, this should work:

assert(isrow(mydata), 'data is not row vector');
set_param(char(my_table), 'Table', ['[', num2str(mydata), ']']);

Note that depending on the values in mydata you may need to tweak the format string of num2str to get an accurate representation of the numbers as text.

Mr/Mrs Guillaume i used your example and worked as well. My problem was: at the block Synchronous Machine pu Standard, i wanted to use the command "set_param" in order to change the parameters which are tables.

Thank you for your help!
