For this purpose, use From Workspace block. Check how I formed the data inside the block. Hope this helps. Let me know if it works for you.

hi ....thankyou firstly...but unfortunately i m not able to read the attached file...:( can you help me to do so ???

[Birdman]

Right click on the file and select Save as. Then save it to your current directory and open it and run.

:(

[Birdman]

Erase the (1) part from the name and try to reopen it.

[sadia qasim]

i could not understand ...which one part are you talking about???

[Birdman]

The model name is inputArray(1). Rename the model as inputArray by deleting the (1) part.

thankyou soo much birdman ..you made my work easier ....thanks for your cooperation..... but when i tried to set this in my model the display shows something else..... i have send you two model ... in model p1 : i used from workspsce block ..the same way as you showed ...but output seems to be something else .. in p2 model : i used constant block and declared matrix as input parameters ....but also did not work .. Dd= [0.6096 1.219 1.8288 2.4384] This is the input ...and the output is SR and it should display this values ,SR = [1.704 1.682 1.669 1.66]....

[sadia qasim]

plzz tell me which block should i use to set this array as input ( from wrokspace block or constant block) ..also SR (output) is my speed ratio which i want to see graphically which respect to Dd (input). please help me out ...

[Birdman]

When you use From Workspace block, you need to provide a time vector, which should be your first column. I set it. See how I did it. Now it works.

[sadia qasim]

you can see in the model that given Dd= [0.6096 1.219 1.8288 2.4384] as input, each value of this array will get divided by the constant 12.19214826 and ouput will be SR = [1.704 1.682 1.669 1.66].... But in your p2 edited file (using from workspace block) i can just see only one value gets displayed and in the worspace output is plotted with respect to time ..... I Have mention everything in the model ...please check it and help me to solve this either by workspace or constant....
