MATRIX (TypeOfMatrix,DimensionsOfMatrix,SeedValuesToUse,IJFunction,PreParameter,IsItInternalCall)

• is the type of the matrix.
• is the order of the Block diagonal matrix.

## Description

• This function gives matrix of order 3 which is satisfying the property of the block diagonal matrix.
• A block matrix is a matrix that is defined using smaller matrices, called blocks.
• For e.g.,

where A, B, C, and D are themselves matrices, is a block matrix.

• Two block matrices have the same shape and their diagonal blocks are square matrices, then they multiply similarly to matrix multiplication.
• In Calci, MATRIX("BLOCK-DIAGONAL") is showing the matrix of order 3 with the entry of 0.
• Users can change the order as well as the entries of that matrix.

## Examples

• MATRIX("block-diagonal",3)
 0 0 0 0 0 0 0 0 0
• MATRIX("BLOCK-DIAGONAL",4,5..7**2)
 5 6 7 5 6 7  0 0 0 0 5 6 7 5 6 7  0 0 0 0 5 6 7 5 6 7  0 0 0 0 5 6 7 5 6 7
