I have a matrix with decimal values.
say:
a=[43 75 23;85 34 78;13 78 23]
i want to convert all the values to 32-bit single precision floating point value IEEE 754 format. Can anybody help me...
or just take a=240;
i want to get "01000011011100000000000000000000"
i referred this link. http://www.h-schmidt.net/FloatConverter/

Not enough bits there. 32 bits is 4 bytes, but you have given a 3 x 3 matrix.

t = uint8(a .');
typecast( t(:), 'single')
and then reshape the result as appropriate.
Be sure to check the byte order against the other possibilities.

it is showing the following error.
Expression or statement is incorrect--possibly unbalanced (, {, or [.

Fixed now. I don't know how the extra comma got in there.

This shows the bit pattern of 240 represented as single precision float:
dec2bin(typecast(single(240), 'uint8'))
