how to define the input to the simulink from workspace as a columns?

I want to call signal from workspace to the simulink using "from workspace block" my input file in the workspace contain 5 columns but when I used block from workspace to call it in the simulink the simulink dont understand it as a columns,

so my question is how to upload my columns from workspace to the simulink in such a way the simulink can diagnose it as a columns?

need help plz

Confirm my understanding..

 - You have a variable in the workspace with 5 columns and n rows
 - You want to provide individual column vectors of this variable as inputs to signals using from workspace blocks

is that right?

See the implementation (attached) of the From Workspace blocks to split the matrix

thanks for your help.. I just tried it I got two types of error that

Error evaluating parameter 'VariableName' in 'From Workspace'

and

Undefined function or variable "a".

actually (t) and (a) refer for what?

e.g.

a = [1,2,3,4,5;6,7,8,9,10];
t = [0;1];

& do the necessary solver settings for two time steps for this test example
