je ne sais pas programmer en pascal mais juste un pt astuce pr programmer la multiplication de deux matrices.

program produitde2matr;
uses wincrt;
var MatrA, MatrB, ProdMatr: array [1..3] of integer;
i,j,k: integer;
BEGIN
for i := 1 to 3 do
for j := 1 to 3 do
readln (MatrA[i,j]);

for i := 1 to 3 do
for j := 1 to 3 do
readln (MatrB[i,j]);

for i := 1 to 3 do
begin
ProdMatr := 0;
for j := 1 to 3 do
begin
for k := 1 to 3 do
prodMatr[i,j] := ProdMatr[i,j] + (MatrA[i,k]*MatrB[k,j]);
end;
end;
END.
