% V,Ma,Vmin,delta,y : matrix of 39*1
% H ,p : matrix of 46*1
X=10;
if Vmin(:,:) < V(:,:) < Ma(:,:) , abs(H(:,:)) < P(:,:), x < 382.99 ,abs(y(:,:))< delta(:,:)
r=(x/382.99)
else
r=inf
end

You can only put one condition in the if statement.
I suggest you read
doc if

hi,
The cylist just answered , anyway you need "AND" Boolean operator :
if (Vmin(:,:) < V(:,:)) && (V(:,:) < Ma(:,:))

You must define the logical relationships between the conditions

if expression % your expression synax do not comply with matlab
statements
else
statements
end
The expression can not use "Vmin(:,:) < V(:,:) < Ma(:,:)" and "," between each expression, change the expression as :
%%if the function of "," is OR ,change "," as "||"
if (Vmin(:,:) < V(:,:)) && (V(:,:) < Ma(:,:)) || abs(H(:,:)) < P(:,:) ||x < 382.99 || abs(y(:,:))< delta(:,:)
% code
end
