 ### Coding a Sci-block
 This section gives hints on how to use Sciscipy in Sandhi to develop blocks. There are two ways of calling Sciscipy from work_function in python.
 
-1. By importing Scilab <br> 
+1. By importing Scilab to use pre-built functions<br> 
 ```python
 from scilab import Scilab 
 sci_obj = Scilab() 
 output_items[0][:2] = sci_obj.rand(1,2)  # This outputs a 1x2 Array of Random number generated by Scilab
 ```
-
+2. By importing Sciscipy to to perform a task in scilab and then return output to python<br>
+```python
+import sciscipy
+
+# Function returns random number generated array computed from scilab.
+def my_sci_func(x, y):
+	# Write your scilab code as strings
+	code_statement1 = "x =" + str(x) + ";"
+	code_statement2 = "y = " + str(y) + ";"
+	code_statement3 = "z = rand(x,y);"
+	combined_statement = code_statement1 + code_statement2 + code_statement3
+	sciscipy.eval(combined_statement)
+	
+	# function return value
+	z = sciscipy.read("z")
+	return z
+
+output_items[0][:2] = my_sci_func(1,2)
+```
+we realize this is the not the best way to code, but _if it works, it works_
