How to define array in Fortran 77?
Arrays
1An array is a named collection of elements of the same type.
2) An array name is a symbolic name for the whole sequence of data.
3) An array element is one member of the sequence of data.
4) An array element name is an array name qualified by a subscript.
5) An array declarator specifies the name and properties of an array.What is the formula for matrix addition?
Now, the sum of the two matrices A and B is given as: A+B = [aij] + [bij] = [aij + bij], where ij denotes the position of each element in ith row and jth column.
The dimension of the sum matrix, that is, A + B is also 'm × n'.Many scientific computations use vectors and matrices.
The data type Fortran uses for representing such objects is the array.
A one-dimensional array corresponds to a vector, while a two-dimensional array corresponds to a matrix.
