how to make a local variable "dialVal" to workspace?

Answer 1

[Robert Cumming]

assignin ( 'base', 'dialVal', dialVal )

[dong van duc]

thankyou very much

how to include value "dialVal" in block "from workspace" in the Simulink

Answer 2

[Sachin Ganjare]

"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.

[dong van duc]

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"

Please,help me i have a Matlab Simulink Model which it`s output is Error .This output (error) I have to minimize it( USING GENETIC ALGORITHM ) by controlling three variables(Kp& ki& Kd) which included in the output.Due to this variables I can`t scope the output,and call this output in an M File

Can any one help me please to call this output in an M File. Thanks
