Deux matrices ne peuvent \u00eatre soustraites que si elles ont les m\u00eames dimensions : une matrice \\(m \\times n\\) peut \u00eatre soustraite d'une autre matrice \\(m \\times n\\), et le r\u00e9sultat est \u00e0 nouveau une matrice \\(m \\times n\\). L'op\u00e9ration s'effectue \u00e9l\u00e9ment par \u00e9l\u00e9ment, de sorte que chaque entr\u00e9e du r\u00e9sultat ne d\u00e9pend que des deux entr\u00e9es situ\u00e9es \u00e0 la m\u00eame position dans les matrices d'origine.<\/p>\n<p>Il faut retenir que la soustraction n'est <em>pas<\/em> commutative&nbsp;: en g\u00e9n\u00e9ral, \\(A - B \\neq B - A\\). En r\u00e9alit\u00e9, \\(B - A = -(A - B)\\), donc inverser l'ordre donne le r\u00e9sultat oppos\u00e9. Si l'on soustrait une matrice d'elle-m\u00eame, on obtient la matrice nulle, dont tous les \u00e9l\u00e9ments valent 0.<\/p>\n<p>La soustraction de matrices intervient partout o\u00f9 les matrices mod\u00e9lisent des donn\u00e9es ou des transformations&nbsp;: r\u00e9solution de syst\u00e8mes d'\u00e9quations lin\u00e9aires, comparaison de jeux de donn\u00e9es (par exemple, soustraire une image attendue d'une image observ\u00e9e), calcul des r\u00e9sidus en statistiques, simulations physiques, infographie et apprentissage automatique. C'est aussi l'op\u00e9ration inverse de l'addition de matrices \u2014 ajouter \\(B\\) \u00e0 \\(C = A - B\\) permet de retrouver \\(A\\).<\/p>\n<p>Lors de l'interpr\u00e9tation du r\u00e9sultat, lisez-le position par position : l'\u00e9l\u00e9ment situ\u00e9 \u00e0 la ligne \\(i\\), colonne \\(j\\) de \\(C\\) vous indique de combien l'entr\u00e9e de \\(B\\) est plus petite (ou plus grande, si le r\u00e9sultat est n\u00e9gatif) que celle de \\(A\\) \u00e0 cette position. Les entr\u00e9es positives et n\u00e9gatives peuvent librement coexister dans un m\u00eame r\u00e9sultat.<\/p>\n<h2>Hypoth\u00e8ses, limites et conseils<\/h2>\n<ul>\n<li><strong>M\u00eames dimensions obligatoires&nbsp;:<\/strong> ce calculateur fonctionne avec des matrices carr\u00e9es de taille 2\u00d72 et 3\u00d73.
