## Integration of a Vector...

Hi all

Assume that we have following vectors:

> V1 := [1/9, -5/9, 7/9, 1/9, -5/9, 7/9, 1/9, -5/9, 7/9];

>  V2:=t*V1;

and we want to compute the integral of V2, namely:

>  Int(seq(V2[i],i=1..9),t=0..1);
>

[       5 t  7 t         5 t  7 t         5 t  7 t]
V2 := [t/9, - ---, ---, t/9, - ---, ---, t/9, - ---, ---]
[        9    9           9    9           9    9 ]

Error, (in print/Int) invalid input: IntegrationTools:-GetOptions expects its 1st argument, v, to be of type Integral, but received Int(1/9*t,-5/9*t,7/9*t,1/9*t,-5/9*t,7/9*t,1/9*t,-5/9*t,7/9*t,t = 0 .. 1)

how we integrate from V2? why answer is wrong in my code?

thanks a lot

## Error in program...

Maple

Hi all

I have written the following code in maple to approximate arbitrary functions by hybrid of block-pulse and bernstein functions but it doesn't work properly especially for f(t)=1.0, so what is the matter?

## Special Matrix construction...

Maple

Hi all

How can I produce following matrix by maple?

the order of matrix should be {N*(m+1)}*{N*(m+1)} where N is known constant

thanks for any guide

## Block Diagonal Matrix...

Hi Again

Assume that we have known matrix namely, Q, of order (m+1)*(m+1) and we want to construct following matrix

where 0(bar) is zero matrix of orde (m+1)*(m+1) and New matrix should be of order {N*(m+1)}*{N*(m+1)} where N is known constant.

thanks for any guide

## Special Block and diagonal matrix...

Maple

Hi all.

Assume that a Matrix P is (m+1)*(m+1) known matrix and we want to construct following special matrix

where

and

how can we do it by maple?

Note that the required matrix is of order k(m+1)*K(m+1)

thanks for any guide
