Error evaluating registered method 'SetInputPortDimensions' of MATLAB S-Function 'saob' in 'untitled/Analog Output'. The following is the MATLAB call stack (file names and line numbers) that produced this error: ['C:\Program Files\MATLAB\R2022a\toolbox\daq\daqblks\daqsfcn\saob.m'] [160] ['C:\Program Files\MATLAB\R2022a\toolbox\simulink\ui\studio\config\m\+SLStudio\StartPauseContinue.p'] [0] ['C:\Program Files\MATLAB\R2022a\toolbox\simulink\ui\studio\config\m\+SLStudio\ToolBars.p'] [0]
Caused by:
  • The input of input port 1 needs to be a 1-D scalar, or a 2-D matrix of size N-by-2.
Component:Simulink | Category:Model error
Error in port widths or dimensions. 'Output Port 1' of 'untitled/From Workspace' is a one dimensional vector with 1000000 elements.

It looks like your value of x has 1,000,000 dimensions. Is it a vector based on time? THe constant block should have a scalar put in to it to work. If you want the play a vector that changes over time, you'll need to use a different block like the from workspace block.

Thank you for your reply. However I was trying to load the data in x into the from work space block. Will it work?

sorry, I missed that. The issue is probably that you don't have a time domain vector with x, so x was read in as 1 million element vector with 1 sample per element (instead of a 1 element vector with 1 million samples). If you transpose x into a column vector, and add a time vector, the from workspace should work.
You could also try reading directly from the spreadsheet. You will need to reformat your spreadsheet and again, add a time stamp: https://www.mathworks.com/help/simulink/slref/fromspreadsheet.html
