See this documentation page for information on using a structure as the Value parameter in the Constant block.

Oops. Looks like the Constant block added support for bus signals only in R2010b. You might want to check if you are able to import your data using the Inport block in your version. Note that you will need to create timeseries objects. It appears that the From Workspace block also supports importing bus signals in the form of a structue of timeseries objects, just like the Inport block.

don't use from workspace, just use a "Constant" block

when i use the Constant block they give me the following error: invalid sitting in 'untitled/constant' for parametre 'value'
this is the value and size of may variable HMM: HMM =
pi: [4x1 double]
trans: [4x4 double]
means: [12x4x4 double]
vars: [4-D double]
mm: [4x4 double]
i will use them in the racognise block in simulink
