Hello

Thanks for accepting me in the forum. You are doing a lot of work in Scilab. I am new to Scilab.

I am trying to go through the following book. But it seems the codes cannot be used directly in Scilab 6.1

Scilab Textbook Companion for
Principles Of Linear Systems And Signals
by B. P. Lathi1

For example the following code:

// s i g n a l s and s y s t e m s
// L a p l a c e T r a n s f o r m x ( t ) = exp (− a t ) . u ( t )n e g a t i v e and p o s i t i v e
syms t s ;
a = 3;
y = laplace ( ’ %eˆ(− a ∗ t ) ’ ,t , s ) ;
t1 =0:0.001:10;
plot2d ( t1 , exp ( - a * t1 ) ) ;
disp ( y )
y1 = laplace ( ’ %e ˆ ( a∗− t ) ’ ,t , s ) ;
disp ( y1 )

I suppose I have to activate symbolic math in Scilab 6.1.

Kindly assist as I am quite new to Scilab.

Thanks & Regards
