"how to include value "dialVal" in block "from workspace" in the Simulink"
You can directly use dialVal directly as it is present in workspace after assignin operation, if I understand your question correctly.

Yes, after assignin operation, "dialVal" is present in workspace, but I have a error when I write "dialVal" into block " From workspace" :
"Invalid matrix-format variable specified as workspace input in 'untitled/From workspace'. The matis must have tow dimensions and at least two columns. Comples signals of any data type and non-double real signals must be in structure format. The first column must contain time values and the remaining columns the data values"
