如果已經安裝了IMSL,在你編寫的程式中使用use 語句呼叫你要用的函式所在的庫就可以了.

下面是抄了的一個例子:

!lin_sol_gen_int 為IMSL mod檔案,在include目錄下

use lin_sol_gen_int

use rand_gen_int

use error_option_packet

implicit none

! This is Example 1 for LIN_SOL_GEN.

integer, parameter :: n=32

real(kind(1e0)), parameter :: one=1e0

real(kind(1e0)) err

real(kind(1e0)) A(n,n), b(n,n), x(n,n), res(n,n), y(n**2)

! Generate a random matrix.

call rand_gen(y)

A = reshape(y,(/n,n/))

! Generate random right-hand sides.

call rand_gen(y)

b = reshape(y,(/n,n/))

! Compute the solution matrix of Ax=b.

call lin_sol_gen(A, b, x)

! Check the results for small residuals.

res = b - matmul(A,x)

err = maxval(abs(res))/sum(abs(A)+abs(b))

if (err

write (*,*) "Example 1 for LIN_SOL_GEN is correct."

end if

end
