i have a table(1024x2) table varible array (1618x1616 uint16) one column in table is having integer value and another column is having corresponding floating point value i want to replace the value in integer array with that table value

i have a table(1024x2)and varible array (1618x1616 uint16) one column in table is having integer value and another column is having corresponding floating point value .i want to replace the value in integer array with that table integer value which is floating point. eg a= 1 2 3 table value 1-50.3 2-80.6 3-50.3 result should be like b = 50.3 80.6 50.3

In the special case where the first column of the table variable is the consecutive positive integers

temp = Table(:, 2);
Output = temp(Variable);

If not then

   [tf, idx] = ismember(Variable(:), Table(:, 1));
   temp = Table(:, 2);
   Output = reshape(temp(idx), size(Variable)) ;

Iam new to MATLAB,that table is having consecutive positive no but that array is having only few of that positive number which is to be replaced ,it is like find and replace kind of thing,that array is also like image Digital count value

[Walter Roberson]

The second set of code should work for you.

Hard to tell what the OP has, but if "table" means the table datatype, then I suspect some of thos parentheses will need to be braces, for example

ismember(Variable(:), Table{:, 1})

[Walter Roberson]

That could be the case. If it is a table data type, then I would expect that there would be solutions using innerjoin()
