You must be trying to do this within a partial post back.

You should do it like this.

  ScriptManager scriptManager = ScriptManager.GetCurrent(Page);
  if (scriptManager != null && scriptManager.IsInAsyncPostBack)
  {
    //if a MS AJAX request, use the Scriptmanager class
    ScriptManager.RegisterStartupScript(Page, Page.GetType(), scriptKey, script, true);
  }
  else
  {
    //if a standard postback, use the standard ClientScript method
    Page.ClientScript.RegisterStartupScript(Page.GetType(), scriptKey, script, true);
  }

The second method is deprecated. Where in the page life cycle are you calling this code?

try without the script tags. I believe the script manager adds that automatically

script = @"function onBeginRequest myJavascript{
//bla bla
                        }


                this.Page.ClientScript.RegisterStartupScript(this.GetType(), "frmulaMatrix", script, true);
