in this function,

i want to generate random integer matrices.

how can do this?

[KSSV]

Generate a vector with that and reshape it to matrix.

[Brian Kim]

Upon execution, matrix' elements are 'double'. It is not 'double', must be 'integer'.

[Walter Roberson]

Which integer data type does it need to be? int16?

[Brian Kim]

ex) 4,6,7,9,10, ~~~

[Walter Roberson]

As I indicated, the routine you are looking at is not suitable for the case where you need the random values to be integral. The link I provided shows the needed code.

randfixedsum cannot be used to generate integers fairly.
