rfor the above program,
I want the output as

how to do this in matlab? please help
A matrix with blank space in Matlab refers to a matrix that contains one or more empty elements, represented by either a single space or a zero value. This means that the matrix has a certain dimension, but some of its elements have not been assigned a value.
To create a matrix with blank space in Matlab, you can use the "zeros" function to initialize a matrix with all zero values, and then manually replace the desired elements with a single space or a zero value. Alternatively, you can use the "NaN" function to create a matrix with blank space, where the empty elements will be represented by "NaN" (not a number).
A matrix with blank space can be useful for representing missing or unknown data in a dataset. It can also help to maintain a consistent matrix size when performing operations on matrices with different dimensions. Additionally, the "NaN" value can be used to indicate invalid or undefined calculations, allowing for easier error handling.
You can access a specific element in a matrix with blank space by using its index position within the matrix. For example, if you want to access the element in the second row and third column, you would use the syntax "matrix(2,3)". If the element is represented by a single space, it will be displayed as an empty string, and if it is represented by "NaN", it will be displayed as "NaN".
Yes, you can perform mathematical operations on matrices with blank space in Matlab. However, it is important to note that some operations may be affected by the presence of empty elements. For example, the "sum" function will return a sum of all non-empty elements, and the "mean" function will return the mean of only the non-empty elements. It is important to handle empty elements appropriately to avoid errors in calculations.
